Windows Mouse Button Techniques

Clicking is pressing and releasing the left button on the mouse. This usually

selects something. Double-clicking is clicking twice in quick succession, and this usually selects something and initiates some action, such as running a program. Right-clicking is clicking the right mouse button, and this usually causes a context-menu to appear. The context-menu is also known as a pop-up

menu.

Checking AutoCAD System variables for ProSteel 3D

A few AutoCAD variables should be checked and modified if necessary before starting a ProSteel 3D work session.

MEASUREMENT = 1 specifies whether to use the imperial or metric system (0 = imperial, 1 = metric)

PROXYGRAPHICS = 0 controls whether proxy graphics are to be created in addition to the ProSteel 3D objects when working with ProSteel 3D. These proxy graphics enable viewing of the ProSteel 3D objects when using only raw AutoCAD by itself to load the drawing.

0 = create no proxy graphics, 1 = create proxy graphics

Checking ProSteel 3D Options

A few default settings have to be specified for ProSteel 3D as well, which

control the display of these objects. Of course, any of these default settings for either individual or multiple objects may also be edited after the insertion.

Right-click while the cursor is located within the drawing area to navigate to the “ProSteel 3D Options” dialog. First select “ProSteel 3D” on the context sensitive menu and then the flyout cell named “Options”.

Some Typical ProSteel 3D dialog box buttons

There are at least 5 buttons that are typical to most ProSteel 3D 17 dialog boxes. The button icons are as shown & explained below:

This is the OK button. Use it to accept and OK all user information when using any ProSteel 3D dialog box. This button will finish a ProSteel 3D command and close the dialog box.

(6)

This is the CANCEL button. Use it to break out of any ProSteel 3D command that you do not want to complete.

This is the HELP button. Use it to find ProSteel 3D Help on the topic that relates to the dialog box being used.

This is the TEMPLATE button. Use this button to store and retrieve dialog box settings that you wish to use on future projects, or re-use from previous projects.

These are the SWITCH ON ROLLOVER, and the SWITCH OFF

ROLLOVER buttons. These are used to automatically minimize and maximize the dialog boxes, allowing you to see more of your ProSteel 3D model.

The ProSteel 3D / AutoCAD Template file

The installation of ProSteel 3D will automatically create a prototype drawing, which will be used as a template for further work. This file copied to the template directory of AutoCAD during installation is called a template and is named “PS170_Metrisch.dwt”.

This template contains a few settings specific to ProSteel 3D such as text styles and dimensioning styles. If the user wishes to alter default settings, this template can be modified with the corresponding settings and saved again as a new template file e.g. CompanyInitials_Metric.dwt

This drawing is an isometric view of the ProSteel 3D model that we will create during this training course.

In this exercise, you learn to create a new ProSteel 3D drawing, based on an existing template, and you will save the drawing with an appropriate name.

1. Start ProSteel 3D by double-clicking the corresponding ICON on the windows desktop.

2. Once AutoCAD has started, and the ProSteel 3D software completed loading, from the AutoCAD FILE pulldown menu, choose New (you could also type NEW at the command line, or use the QNEW icon located on the AutoCAD Standard Toolbar)

3. You will now see the “Create New Drawing” AutoCad dialog box. Pick the “Use a Template” icon from here, and from the list of templates shown, choose “PS170_Metrisch.dwt”. You will now be in a brand new drawing ready for you to start crating your ProSteel 3D model for the remainder of this course.

Note: When starting ProSteel 3D from the desktop icon, the default drawing opened is already using the template “NZ_Metric.dwt”. You can view the properties of the ProSteel 3D desktop icon to check this. Right-click on the ProSteel 3D desktop icon and check the Properties. The template used is defined after the /t argument.

(8)

4. Use the AutoCAD SAVE command to save your drawing with the name “1234_Model1.dwg”. The first time you use the SAVE command within a new AutoCAD drawing, you will actually be presented with the “Save

Drawing As” dialog box. Save the drawing in the MyJobs folder found on the desktop.

5. If your new ProSteel 3D drawing has been started correctly, you should see a 3D UCSICON in the bottom left hand area of model space. As per

AutoCAD, ProSteel 3D will have created 2 paperspace layouts for you, called Layout1 and Layout2. These 2 layouts need to be setup using the AutoCAD Page Setup dialog box if you wish to have paperspace views of your 3D models.

6. Your drawing should now be saved as C:\Documents &

Settings\Student\Desktop\1234_Model1.dwg Leave your drawing open, ready for the next chapter.

Setting the Work Frame

Any ProSteel 3D model creation should be started by creating one or several so-called Workframes.

These workframes facilitate easy spatial 3D orientation because they can depict the basic system dimensions (e.g., axes dimensions) in the form of design aid objects as well as automatically creating the associated UCS system for each of the views as defined by the work frame.

Users simply select the mouse button to change the view.

ProSteel 3D for AutoCAD offers the parametric creation of rectangular shapes and traditional hangar/portal frames as well as the creation of cylindrical, segmented, pyramidal or tapered steel frames. (Some predefined workframes are also available via the Template button within the Workframe dialog box.)

It is possible to create multiple work frames and their associated UCS systems within one model drawing. This requires a different group name (Workframe name) for each work frame system.

ORKFRAME

In this exercise, you learn to create a rectangular workframe as a base for the platform area of your ProSteel 3D model.

1. Open your previously started ProSteel drawing called 1234_Model1.dwg, and from the ProSteel 3D Utilities toolbar, choose the Workframe icon, or pick Workframe from ProSteel 3D / Additions pulldown menu.

2. When prompted for the Workframe origin point, use the point 0,0,0 as a source. Enter the X-axis as requested by pointing, with Ortho set to on.

3. The “WORKFRAMES” command uses a dialogue box for the input of design data. Create the Workframe using the following values:

4. Create an axis label as well to improve the orientation within the workframe. Use the following values:

(18)

The result of the Workframe command can be seen in the screenshot above. Selecting a magenta-colored line shows that we are dealing with areas and not simple lines. These areas can be edited as ProSteel 3D objects. If such an object is moved or copied, the associated properties and UCS system are retained. The workframe is located on the PS_FRAME layer, which is write protected (locked) by default.

5. Unlock layer PS_FRAME, then click on one of the magenta-colored areas and then right-click to the context menu and click “ProSteel 3D Properties”

Only those options are checked in the LAYOUT folder, which are selected as the default in the Options. Any additional information to be displayed for the selected element can be specified here subsequently.

6. Select options on the LAYOUT folder of each Workframe Properties dialog box to view diagonals, cutting plane, source, etc. for a work frame and track any of the changes directly on screen.

Load the PROPERTIES of the ProSteel 3D Workframes and construction lines to effect subsequent parametric changes for a work frame.

Differently shaped workframes that cannot be defined with these dialog boxes can be defined with the help of normal AutoCAD lines. The associated definition areas for the UCS systems can be created subsequently using ProSteel 3D commands.

(19)

7. Adjust the PROPERTIES of your ProSteel 3D Workframes to reflect the following values (change the Name box under the Data folder):

Change Zone1_Front to Zone1-GridA, Change Zone1_Side_L to Zone1_Grid1, Change Zone1_Side_R to Zone1_Grid2,

Change Zone1_Top to Zone1_Platform_level

(Refer back to Exercise 03-1, part 6 for adjusting workframe properties)

ORKFRAME

In this exercise, you will add a rectangular workframe as the portal frame / hangar area of your ProSteel 3D model.

1. While in the current drawing called 1234_Model1.dwg, and from the ProSteel 3D Utilities toolbar, choose the Workframe icon again, or pick Workframe from ProSteel 3D / Additions pulldown menu.

2. When prompted for the new Workframe origin point, pick rear bottom left point of the existing workframe as a source. Enter the X-axis as requested by pointing, with Ortho set to on, to the current X direction shown by the UCSICON.

3. Fill in the values on the ProSteel 3D Workframes dialog box as shown below.

(21)

4. Ensure that the 5000 height to the hangar area has 2 unequal divisions, by unticking the Height button, and filling in the values as shown to the Height Axis Distance area of the dialog box, as shown below:

5. Within the Axis Descriptions tab, ensure that the Y-Axis start value is set to B.

6. Now adjust the PROPERTIES of your new workframe (as you did in exercise 03-1) to reflect the following values:

Change Zone2_Front to Zone2-GridB, Change Zone2_Y_1 to Zone2_GridC, Change Zone2_Back to Zone2_GridD, Change Zone2_Side_L to Zone2_Grid1, Change Zone2_Side_R to Zone2_Grid2,

Change Zone2_Bottom to Zone2-Lower_Level, Change Zone2_Z_1 to Zone2_Mid_Level, Change Zone2_Top to Zone2_Top_Level, Change Zone2_Roof_L to Zone2_Roof_Left, Change Zone2_Roof_R to Zone2_Roof_Right.

(Refer back to Exercise 03-1, part 6 for adjusting workframe properties)

In recent versions of ProSteel 3D, you are also able rename workframe names via AutoCADs Properties dialog box. You may wish to test this.

7. Now SAVE your ProSteel 3D model before moving on to the next exercise. The result of this second

Workframe command can now be seen in the screenshot at left.

(22)

Selecting Views

Use this command (the “ProSteel 3D Select View” command) to select the views defined via the work frames or add new views to the selection list.

Once a view is selected, ProSteel 3D places the UCS into the selected work plane and displays the 3D model as if this plane is viewed vertically. The

specified cutting planes are activated at the same time so that only the objects within this area are visible.

Note from the “Choose View” dialog box shown above, that you can either set views, or set UCS.

The SET VIEW button aligns your viewpoint so that you are looking perpendicular at the selected view, and it sets the UCS square to that view.

The SET UCS button only changes the UCS orientation, it does not re-align the view.

Note also from the “Choose View” dialog box shown above, that you can delete existing Workframe views and create new workframe views from any direction.

In this exercise, you learn to navigate to your workframe selected views, with or without a relevant UCS

1. From the ProSteel 3D Viewtools toolbar, choose the Select View icon, or pick Choose View from ProSteel 3D / Zoom-Views pulldown menu.

2. Check that your Choose View dialog box has view names that match those in the diagram below:

3. Try the following clickable commands within the Choose View dialog box, after selecting a named view:

Set View: Sets the selected view (the relevant cutting plane is activated)

Set UCS: Sets the selected UCS only (the current view remains the same)

4. From the ProSteel 3D Viewtools toolbar, choose the Isometric Overview icon, or pick Isometric Overview from ProSteel 3D / Zoom-Views pulldown menu.

Note the black arrow in the corner of the icon above. If you click and hold this icon, you will be presented with 5 alternative Isometric View icons, which allow you to view your workframe or model from 5 distinct isometric locations.

(24)

The Clipping Plane

Working with a 3D model can quickly become complex, especially if many parts are spatially stacked or overlap one another. ProSteel 3D offers a command to hide parts in front of and behind the current work plane – the so called clipping plane.

This facilitates the design process since only those objects are visible that are close to the same work plane and prevents the accidental manipulation of stacked shapes. The term ‘approximately’ is here used in the sense that only the objects within the cutting plane distance of 500mm specified in the “work frame” are visible to the front and rear. If one of the defined views or an object view is selected, the hide option is activated as the default setting unless the command has been deactivated globally.

Sometimes it is however also reasonable to look at all component parts of the model in the depth – to have an overall orientation. This is the reason why this function can be switched on and off.

Clipping planes (or cut planes) can be turned on or off, adjusted for distance, or flipped by using the Clipplane command under the ProSteel 3D / Zoom-Views pulldown menu.

Inserting Shapes

Here are a few basics concerning the insertion of shapes, before starting with the construction of your sample model:

Shapes can be accessed by picking the Shape button on the ProSteel 3D Elements toolbar, or by picking Shapes under the ProSteel 3D pulldown menu.

You are then presented with the following dialog box:

For STRAIGHT SHAPES, first, select a shape type and size – the desired shape cross-section appears in the preview area, together with the insertion points. The selected insertion point is displayed in red. The drop down list of materials is available for use with the shapes, and user shapes.

There are two different methods of inserting shapes:

- Cross-section of the shape is located within the current UCS; the length is specified with parameters.

- Shape is defined by indicating start and end points (via coordinates, clicking, object snap, or line specification)

The position of the shape can be preset via the basic position , 90 degrees, etc. or directly on screen when inserting the shape if the “Orientate after

(28)

Bent Shapes (shapes that are bent to form a curve) can be achieved by using the BENT SHAPES tab on the “ProSteel 3D Shapes” dialog box:

Bent shapes can be placed by picking existing AutoCAD arcs , or by picking 3 points to define center of arc, start and finish of arc.

Orientation of shapes can be controlled at the time of placing shapes by carefully setting options on the OPTIONS tab of the “ProSteel 3D Shapes” dialog box:

HAPES

In this exercise, you learn to select and insert shapes, and orientate them to their desired position.

1. First orientate your sample model view into an isometric overview.

Remember, you are using drawing 1234_Model1.dwg, in case it needs to be opened.

2. From the ProSteel 3D Elements toolbar, choose the Shape icon, or pick Shapes from ProSteel 3D pulldown menu.

3. Insert a shape by cross-section by setting the “Length” to 1000 and then clicking the “Insert Shape as Cross-Section with Specified Length” button.

Pick the Shape Base Point in your model, and when prompted at the

command line, choose the 2 Point method to orientate the shape. Click the 2 points on screen and the shape is now inserted in a negative Z direction.

4. Confirm the orientation of the shape by clicking the left mouse button

several times after the shape appears. Confirm your desired orientation with a right mouse button click. To finish the command, you need to click the OK button on the ProSteel 3D Shapes dialog box.

5. Now insert a second shape. Set the “Length” to 0 and this time exit the dialog with the “2 Points” button.

Now pick two points on screen and agai n orientate the shape as desired by left mouse button clicks. When the dialog box returns to the screen, finish the command by clicking the OK button.

(30)

6. Insert a third shape parallel to a line, e.g. the front perpendicular line of the current work frame. Execute the “Shape” command and click the “Line” button.

Now pick the desired AutoCAD line or work frame. Again use several left mouse button clicks to orientate, and then finish the command with the OK button.

(31)

Creating Plates and Polyplates

Plates with any desired form are called Polyplates by ProSteel 3D and can be inserted into the model in addition to the preset standard shapes.

The plate dimensions can be defined either by picking points or by adopting an existing polyline. If a polyline is adopted, plate contours containing radii are possible as well. The plate dimensions, when dealing with rectangular plates, can be created parametrically in the LENGTH/WIDTH field as well. This also enables the definition of an insertion point for the plate.

Plates can be accessed by picking the Plates button on the ProSteel 3D

Elements toolbar, or by picking Plates/Plates under the ProSteel 3D pulldown menu.

For STRAIGHT PLATES, first, select a plate size – the desired plate plan-view appears in the preview area, together with the insertion points. The selected insertion point is displayed in red.A drop down list of Materials and Labels is available for Plate call-up.

Arc Plates (plates that are extruded to form a curved plate) can be achieved by using the ARC PLATES tab on the “ProSteel 3D Plates/Polyplates” dialog box:

(32)

Arc Plates can be placed by picking existing AutoCAD arcs , or by picking 3 points to define center of arc, start and finish of arc.

2. Create an 800 x 400 x 20 thick plate simply by entering values in the applicable cells in the Straight Plates tab of the ProSteel 3D

Plates/Polyplates dialog box. Choose a relevant insertion point from the preview panel at the right of the dialog box, and ensure Grid is unticked. Now click the “Inserts a Rectangular Plate on a Insertion Point”, and follow the prompts at the command line to place the plate.

When the dialog box returns, finish the command by clicking the OK button at the bottom left of the dialog box.

3. Create a 4 sided plate by clicking the “Inserts a Plate by Four Points” button. Be sure to follow the prompts for corner points on the AutoCAD command line, as the order is not sequential.

When your plate looks correct, be sure to finish with the OK button.

4. Draw a closed polyline of any shape, containing at least 6 straight line segments. The polyline may contain fillets or arcs if you wish. Now click on the “Inserts a Plate by Selected Polygon, Circle or Arc” button in the

Straight Plates tab of the ProSteel 3D Plates/Polyplates dialog box.and follow the command line prompts. Finish by clicking the OK button

Properties

Around six index cards are available as tabs if the ProSteel 3D properties of a shape or plate are queried. They are: Layout, Shape Type, Data, Position, Assignment and Analysis View.

ProSteel 3D users can query the properties of any ProSteel 3D object by double-clicking the object. You will be presented with the appropriate ProSteel 3D dialog box. (Ensure that Double Click Edit is enabled on the Options tab of the ProSteel 3D Options dialog box)

Another method to query the properties of a shape, is to click the shape to highlight it, then right-click your mouse to invoke the context sensitive right-click menu, similar to that shown:

Click the PS3D Properties command on the right-click menu to invoke the relevant Properties dialog box.

Layout: Change the shape type, size, and display mode by selecting the desired value in the pull-down menu.

Display: Six different displays are possible for individual or any number of shapes, WITHOUT any loss of information (see illustrations below)

Only centerline

Holes: As needed, drill holes can also be shown in different display levels or may be ignored all together. The information itself remains intact, of course. There are 5

(37)

as “Extruded Circle”. Holes that have no bolts, such as at a baseplate, are generally displayed as “Real Holes”.

Options: In addition, it is also possible to display a variety of additional information, as shown in the dialog box displayed on the previous page. Part Labels (text indicating part type) can be displayed, part centerlines can be turned on, etc,etc.

Shape Type / Position: The shape may be exchanged with another shape type and/or another shape size at any time. The dimensional sizes of plates can be altered. All manipulated elements such as drill holes, polycuts, ribs, plates, etc., are taken into account automatically

You can also add a slope to a Shape Type by using the Conical tab.

Data: All data with relevance to the parts lists are depicted here, and if needed, may be supplemented or changed. Any shape modification results in an automatic recalculation of the data. See the dialog boxes displayed below.

(38)

Position: Position, insertion point or points, and rotation angle can be subsequently changed and edited for any already inserted shapes. This makes it easy to correct an incorrectly inserted shape at any time. See the dialog boxes displayed below.

Assignment: You can change the assigned detail style, display class, area class and part family of the shape from this tab.

(39)

Analysis View: The analysis tab permits you to modify the static effect lines of the shapes to get an optimum export for the transfer to static programs. You can force the output of analysis display at the different interfaces, and these effect lines defined by you are exported instead of the center lines of the shape.

More on Properties

If a shape has been modified after its insertion, by applying drill holes, cutouts, outlets (gaps/notches), Boolean operations or if the shape has been assigned to a construction group, additional tabs appear on the Shape Properties dialog for every type of element modifier. The manipulation data can then be viewed, edited or deleted.

Due to the utilization of structured dialog boxes, it is possible to track any changes directly on the screen while entering the change when editing a manipulation. The properties of the component parts are event controlled, which means that the individual tabs are only available when the component part has been manipulated or edited.

As one can see, almost any type of information about a given object can be controlled comfortably within one single dialog box.

A context–sensitive online help is always at your fingertips. Please use the help buttons located on some ProSteel 3D dialog boxes, and on the pull-down menu.

(40)

A variety of comfortable and easy to use editing commands are available in ProSteel 3D as well as the possibility of manipulating all component parts via AutoCAD commands.

All manipulation commands are arranged clearly within the “Element Modification” dialog box, and can be accessed individually on the “Modify 1” and “Modify 2” toolbars. The range of editing commands can also be accessed via the ProSteel 3D / Manipulate pull down menu.

In this exercise, you learn to use some of the editing commands on the Element Modification dialog box.

1. First orientate your sample model view into an isometric overview. Remember, you are using drawing 1234_Model1.dwg, in case it needs to be opened.

2. Draw a 3000mm length of 360UB45 beam, down on the ground next to your building model. Use any position point on the UB that you like.

3. Open the Element Modification dialog box via the icon shown below. You can also find many of the commands to be used in this exercise by choosing editing commands from the ProSteel 3D / Manipulate pulldown menu.

4. Under the Divide/Connect area of the Common tab of this dialog box, set the distance to 25, then click the DIVIDE button. When asked at the command line to choose the shape to be divided, pick the 360UB. When asked to pick the Dividing Point, osnap to the midpoint of any edge of the 360UB. The 360UB is now divided into two separate shapes, with a 50 gap between them (2 x 25), as shown below.

This button is on the Element Modification dialog Common tab.

5. Use the Lengthen Shapes command to lengthen the new right hand shape. Set the default to 200, click the LENGTHEN SHAPE BY DEFAULT VALUE button, and then left click the right hand end of the right hand shape 5 times in a row. The 360UB should now be 1000 longer (5 x 200).

This button is on the Element Modification dialog Shapes tab.

6. Now use the Shorten Shapes command to shorten the left hand shape. Set the default value to 100, click the SHORTEN SHAPE BY DEFAULT VALUE button, and then left click the left hand end of the left hand shape 5 times in a row. The 360UB should now be 500 shorter (5 x 100).

(42)

7. The 360UB’s should now appear as shown below.

8. Now draw two 360UB transverse beams, each 2000 long, and both at 90 degrees to the previous beam. Place them as shown below. Do not try to adjust the beam intersections just yet.

9. Now choose the CUTS 2 OBJECTS TO BI-ANGULAR CUT USING OPENING ANGLE BETWEEN BOTH button (The Angle Bisect Button) from the Mitre Cuts area of the Element Modification dialog box to clean up the left hand beam intersection. When you are asked for the First Shape to Anglecut, and the Second Shape to AngleCut, click the two left hand beams near the ends where they meet, and the beams will now meet as if they were Mitre Cut.

10. Now we will cope the end of the right hand long beam to fit the profile of the right hand short beam. Pick the ENABLES TO COPE ONE SHAPE TO ANOTHER button (Cope Button) from the Other area of the Shapes tab of the Element Modification dialog box.

When asked to pick the Second Shape to add a Cope, left click the long beam near the right hand end. When asked to select the Shape on Which to Add a Cut, left click the short right hand beam. A cope is now applied to the first beam, but you will be presented with the ProSteel 3D Cope dialog box in order to sort out dimensions. Set the values as at left. Now click the OK button on the dialog box to complete this

task. If you do not achieve the wanted results after setting the values as shown, use the AutoCAD UNDO command to erase the Cope, and then try the command again.

12. We will now create a 10mm wide vertical notch at the right hand end of the SHS. Zoom to this right hand end, and now pick the ENABLES TO CUT AN OBJECT BY USING OUTLETS button (Notch button) from the Other area of the Shapes tab on the Element Modification dialog box.

Select the SHS at the right hand end when prompted. When prompted for the

Insertion Point for Notch, osnap to the bottom midpoint edge at the right hand side. When you now see the ProSteel 3D Notch dialog box, fill in the values as shown below: (as you change the values, the notched end of the SHS is visually being created)

Click the OK button to finish the command.

13. The right hand notched end of your SHS should now look like this.

If you wish you could try and add a 10 thick cleat as if was welded into the notch, but you would need to rotate your AutoCAD UCS first. If you are not familiar with rotated AutoCAD UCS’s, ignore this and move on to the last part of this exercise. If you understand UCS’s, then you could use the ProSteel PLATE command to create the cleat.

14. We will now add a 6mm thick seal plate to the left hand end of the 150 SHS. Zoom to the left hand end of this beam first. Now pick the COVER PLATE button on the Plates Toolbar. You will also find this button buried under the Plate button on the ProSteel

(44)

3D Elements Toolbar. (You can also find COVER PLATE as a command on the ProSteel 3D / Plates pulldown).

15. When you use this command, you will be presented with the Create Cover dialog box. Change the Thickness value to 6, make the offset -4, and then click the Create button. When prompted, click the SHS at the left hand end, and the 6mm thick end plate will be created as shown below.

16. This now completes the Element Modify exercise. You may now wish to use the AutoCAD ORBIT command to not only shade the beams created above, but to revolve around them. When using the ORBIT command, the right click context sensitive menu allows you to not only shade, or perform hidden line removal on your model, but you can also display your model on Isometric mode or in Perspective mode.

Save your 1234_Model1.dwg file back to disk before moving to the next chapter. You can delete your beams before doing this is you wish.

End Plates

The “End Plate” command offers a variety of connection types for connecting two shapes.

Endplates Normal Endplates

Spliced Endplates Flanged Endplates

Endplates with haunches or Bottom Trains

When using the End Plate command, pick the shape where the end plate is to be connected (end section). The next prompt asks for the support shape or complete the command using “ENTER” or “spacebar” or right mouse button. If a support shape is selected, a cut based on the plate thickness is automatically made on the shape, the end plate is added, and a drill hole field is attached to the support shape, if one was selected. The corresponding plate is created at the end section of the support shape if no support shape is selected.

Logical Links

An important work saving feature in ProSteel 3D are the links between individual components and parts, also called "logical links." These links are another characteristic of the object-oriented structure of the program.

Since working with these links requires a certain level of skill we recommend that novice users first focus on the basic functions such as creating and manipulating shapes and creating automatic connections.

What Are Logical Links ?

Logical links are links between ProSteel 3D objects and their modifications. If you modify a component using another component, all components involved know of this "action." When you now modify one of these components, all others will adjust accordingly. You can also change the entire modification settings by accessing the corresponding link.

Logical links can save an enormous amount of work when creating 3D

connections as long as the same ‘design laws’ (ie., the type of joint) also apply to the modification. If this is the case, just delete the corresponding link and change the connection manually – the links are an aid but do not have to be used at all times.

Active and Passive Links

There are two types of links listed in the dialog entries: active and passive links.

Passive links indicate that component A belongs with component B. For example, stiffeners and shapes are connected with passive links because the stiffeners do not effect any change at the shape and the shape does not directly affect the stiffeners either.

Active links indicate that component A physically changes or modifies

component B. For example, a mitered cut connects both shapes with active links.

In this exercise, you will add end plate connections to your shapes on Grid A

1. From the ProSteel 3D Elements toolbar, choose the Endplate icon, or pick Endplates Normal from ProSteel 3D / Connection /Endplates pulldown menu.

2. Pick the 250UB31 beam (at the Grid 1 end) to be used as the connection shape, and the 200UB30 column (at the Grid 1 top end) as the support shape. Automatically a connection is created using the last used values, however we will edit these values to our new requirements.

3. Adjust the connection values in the dialog box to match those shown in the dialog boxes below.

(50)

Note that in this instance the values in the Bt. Train folder do not apply as nothing in the Select Haunch pulldown list is ticked on.

4. Save the current plate connection as a template before exiting the dialog box, so that it is possible to reuse those connection values again at another time and place without re-keying. You will need to give the template a sensible name.

Use the Template button at the bottom left area of the ProSteel 3D Endplates dialog box.

5. Apply the same plated connection at the Grid 2 end of the same frame. Your beam ends should look like this:

6. Now insert three shapes to Grid B to match those on Grid A. (200UB30 columns with 250UB31 beam) You will need to use the INSERT SHAPE USING 2 POINTS button on the ProSteel 3D Shapes dialog box to insert the

columns, rather than attach by the INSERT SHAPE ON SELECTED LINE button.

(51)

7. Create haunched connections to both ends of the beams with the following values:

(52)

9. Highlight the 250UB31 beam at Grid B, then click PS3D Properties on the context-sensitive right mouse button menu. (or you could just double-click the beam)

In the Shape Properties dialog box, go to the LogLinks tab, and click the left or right arrows button until the left 200UB30 column is highlighted in white, then click the EDIT CURRENT LOGICAL LINK button.

The ProSteel 3D Endplates dialog box is opened for that connection, and you are able to edit the values. Change the values to create 4 rows of 2 bolts, and change the haunch length to 300. Do the same to both ends of your beam.

You should now have a 3D model which looks something like this: (save your model to your hard disk)

In this exercise, you will add bracing components to your model at Grid A, and Baseplates to all columns.

BRACING: The Bracing command uses system lines and boundary edges to define the geometry of the final brace.

1. Draw a normal AutoCAD line, on an appropriate layer, diagonally from the lower left to upper right junction points, and vice versa. The lower junction point should be 100mm above the bottom of the column, and directly

midway across the face of the inside flange of the column. The upper

junction point should be at the point where the underside of beam, and face of endplate meet, and midway across the underside of the beam.

2. You should now have a Grid A layout which looks like this:

Ensure that the diagonal lines are aligned perfectly to Grid A, by viewing Grid A from all angles. Adjust the end points using normal AutoCAD commands if required.

3. Use the ProSteel 3D Select View tool to set your view to Gid A. Now from the ProSteel 3D Elements toolbar, choose the Bracing icon, or pick Static Bracing from ProSteel 3D / Connection pulldown menu. (Ensure your view is set to the Grid A view)

(54)

4. You are now presented with the “ProSteel 3D Bracings” dialog box. Ensure the values for your bracing matches those shown in the dialog box below.

Pick the bracing button at the bottom left corner of the dialog box. You are now prompted to pick a system line for your brace (Pick one diagonal line only, that running lower left to upper right). Next pick the three border lines of brace members used in this case, they are shown on the diagrams below.

After picking the border lines, and hitting enter, you are presented with a Shape Length Standard dialog box. Round off the Selected Shape Length to something appropriate. (In this case try 4300). At the next prompt, choose Return for End, to accept the previous border lines. Hit enter again, and the bracing cleats and brace members are created and bolted together.

5. Create a similar brace member and cleats in the opposite direction as well. When inserting the brace member, ensure that the shape is not inserted at the “front”, but at the “back” of the cross-braced system, so that the two angle members do not collide.

BASEPLATES: Baseplates are to be attached to the two columns of the frame at Grid A. The values are entered into the “ProSteel 3D DSTV BasePlate” dialog box. The command can also be used to shorten the support shapes by the value of the base plate thickness automatically, or to add holding down bolts (tie bolts).

Note: These bracing components are not logically linked, and as such cannot be modified by double clicking the brace member to get to the dialog box shown at left.

(55)

6. View your drawing isometrically by using the ProSteel icon with the

airplane. Now zoom to the base of the columns at grid A. From the ProSteel 3D Elements toolbar, choose the BasePlates acc DSTV icon, or pick

BasePlates DAST from ProSteel 3D / Connection / Baseplates pulldown menu.

7. Follow the prompts at the AutoCAD command line, “Select Shape to

Connect”, and after selecting the column near the bottom, the ProSteel 3D DSTV BasePlate dialog box will appear. Attach a base plate to each of the two front columns on Grid A, using the values in the following dialog box, to produce the base plate illustrated. (ignore the Data & Dowels tabs this time)

(56)

8. Your 3D model should now look similar to that shown below. Save your drawing to your hard disk.

Note: On the Connect tab of the “ProSteel 3D DSTV Baseplate” dialog box, the WITH TIE BOLTS cell may need to be ticked off then on again, in order for the tie bolt symbols to be inserted on the correct AutoCAD layer (they should turn cyan in colour)

In this exercise, you will add Portal Frame components and connections to your 3D model at Grid D.

1. View your model isometrically (as explained on Exercise 03-3, item 4) and zoom closer to the Grid D area.

2. Insert 2 columns and 2 raking rafters to the workrame lines at Grid D to form a Portal Frame structure. Use 310UB40 shapes, and align the outside mid flange points to the workframe lines.

Note: ProSteel 3D does include a Portal Frame generation command,

however we are not using it in this case, as our Zone 2 Workframe already has linework that can be used for constructing our model. If you would like to explore the Portal Frame generator, you could type the command

PS_FRAME, or click the FRAMES button on the ProSteel 3D Structural

Objects Toolbar. (It can also be found under the Structural Objects area of the ProSteel 3D Elements Toolbar)

3. Now add a base plate to each of your Grid D Portal Frame columns and use the following values to achieve the result shown.

The information on the Data and Dowels tabs are not important in this case.

(61)

4. We now need to tidy up the Portal Frame knees and apex before adding stiffener plates. Use the ANGLE BISECT command available under the ProSteel 3D / Manipulate pulldown menu. Follow the prompts to pick two shapes each time to bisect.

(You could alternatively use the “Cut 2 Objects to Bi-Angular Cut using Opening Angle Between Both” button (the ANGLE BISECT button), under the Mitre Cuts area of the Shapes tab, on the “Element Modification” dialog box.

You may need to zoom to the relevant areas of your model to achieve these mitred cuts. When completed, you should have knees and an apex as shown below:

5. We now need to add stiffener plates to each side of the portal frame apex joint where the two 310UB40 raking rafters meet. To do this we will use the “Stiffener at Angle” command.

Choose the “Stiffener at Angle” icon from the ProSteel 3D Elements toolbar.

Note that the icon shown above may be located as a flyout from the “Stiffener” icon as shown below.

(62)

6. The “Stiffener at Angle” command will prompt you for several points. Choose the points as shown in the diagram below.

Use the following values for the stiffeners in the ProSteel 3D Stiffener dialog box to achieve the result shown.

a. Pick shape where you wish to create stiffeners.

b. Pick insertion midpoint of stiffeners

c. Pick the position line of stiffeners

Note: Do not enter an ANGLE value on the OPTIONS tab, as this is automatically read into the cell by the use of the STIFFENER AT ANGLE command.

To finish the command, ensure that you click the OK button at the bottom left of the ProSteel 3D Siffener dialog box.

(63)

7. Now add stiffener plates to each side of the portal frame knee joints where the 310UB40 raking rafters and columns meet. To do this use the same “Stiffener at Angle” command technique used in item 5 and 6 of this

exercise. Use the same values for these stiffeners as shown in the previous page dialog boxes to achieve the result shown below.

8. Your 3D model should now appear as shown below:

Note: When using this command, you will be asked at the command line to “Select Shape at position to create Stiffeners”. Answer this by clicking the column shape, not the sloping rafter. This will mean that the logical link formed will be the stiffeners to the column (The column structurally is a more important member than the sloping rafter)

In this exercise, you will divide your Portal Frame rafter components and add splice connections to your 3D model at Grid D.

1. Use the SET THE CURRENT UCS ACCORDING TO THE SELECTED

WORKFRAME button on the Select View dialog box to set your current UCS to be aligned to Grid D. This UCS is controlled by your previously created workframe. Remember that in this instance your new UCS is aligned as if you were working from the outside rear side of your model.

Now draw an AutoCAD line that runs from the midpoint knee flange junction on the left hand side of the portal frame, and finish it perpendicular to the workframe line above. Then offset this line 400 to the right. Use the

diagram below to achieve this:

The line shown at Step 3 above will be used to divide the rafter into two pieces, and for locating the required Splice Connection. Use the AutoCAD mirror command to create two similar lines at the right hand end of the portal frame.

2. Leave your current UCS set to Grid D. Now we can add the first splice connection to the right hand rafter. Zoom to the relevant right hand rafter area first. Now click the Splice icon on the ProSteel 3D Elements toolbar to invoke the SPLICE command. (You can also find this command under the ProSteel 3D / Connections / Splice Connections pulldown (SPLICE DAST).

Follow the prompts, Select the shape (the right sloping rafter), now right click to enter because there is no second shape to connect. When asked for the point at which to divide the shape, osnap to the end point of the

previously drawn temporary line (it is the line 400 away from the portal knee, and parallel to the rafter). The rafter is now divided, and the splice created, but you will need to alter the values in the ProSteel 3D Splice Connection dialog box to the values shown on the following page:

(65)

Your right hand rafter should now be shown divided with a 10mm gap, and the completed splice should be a cantilevered diagonal splice consisting of 3 plates (one for seating purposes) and 10 bolts. It should appear as shown below:

Note: You may need to untick and then retick some cells to force ProSteel to change the values. The SINGLE SIDE box is a good example in this case.

Note: Check all welds shown, you may need to erase some welding runs shown around the vertical plates. Weld runs are generally shown as red arrowed lines.

If your mitred cut at the rafter / column junction is deleted, just repeat the Mitre Cut command here to repair.

(66)

3. Leave your UCS aligned to Gridline D and we will now add the second splice connection to the left side of the portal frame. Before doing this you will need to re-orientate the direction of the left sloping rafter (This is because the next splice connection runs in the opposite direction as the previous one). Double click the left sloping rafter. You will be presented with the Shape Properties dialog box. From the Position tab, click the turn button.

This re-orientates the rafter so that it now runs in the opposite direction.If the cuts to each end of the sloping rafter are corrupted, then delete them from the CUTS tab of the Shape Propertes dialog box, then use the MITRE CUT command to redo them. If the knee joint stiffeners or apex stiffeners rotate off normal, erase them and then replace them using the method described in Exercise.07-1

4. You can now place the second splice connection at the left sloping rafter in a similar manner as was done in part 3 of this exercise. Use similar values as before to achieve the following result, but make sure the vertical plate is shifted from the left side to the right side:

5. View your model isometrically (as explained in Exercise 03-3, item 4) and zoom closer to the Grid D area. The Grid D area of your 3D model should now appear as shown below:

Note: Check all welds shown, you may need to erase some welding runs shown around the vertical plates. Weld runs are generally shown as red

arrowed lines.

If your mitred cut at the rafter /

column junction is deleted, just repeat the Mitre Cut command here to repair.

Drilling

In this chapter, you will add Baseplates to columns at Gridline B, and create holes in them by drilling.

Objectives

Add a Basepl ate to columns at Gr i dline B.

Drill hol es through these baseplates, ready for hol ding down bolts.

(69)

Drilling

We can create holes, or patterns of holes, in any shape or plate, to any location, using the ProSteel 3D Drill command. The Drill icon can be found on the “ProSteel 3D Edit” toolbar, or alternatively the “Drill” command can be found under the ProSteel 3D pulldown menu.

It is important to note that the current UCS must be parallel to the plate being drilled, or the portion of the shape being drilled, when drilling is used.

Most drilled holes will have bolts passing through them, so the Drill command will allow you to automatically place bolts as well (if needed), via the ProSteel 3D Drill dialog box.

To set the UCS current to the object, use one of the following icon commands:

“Object UCS Centered” and “Object UCS at Point” commands allow for orientation of a new UCS aligned to the Steel Plate or portion of the Steel Shape to be drilled.

“Face UCS Centred” and “Face UCS at Point” commands commands align the users UCS with any Bodyface by selecting and edge.

To set your current view aligned to the object, use one of the following icon commands:

“Object View Centered” and “Object View at Point” commands allow for the orientation of your current view to be aligned with the Steel Plate or portion of the Steel Shape to be drilled.

“Faceview Centred” and “Faceview at Point” commands commands align the users view with any Bodyface by selecting and edge.

The Object UCS icons, and Object View icons shown above, can be found on the “ProSteel 3D Viewtools” toolbar, or on the “Object UCS” and “Object View” toolbars. Alternatively, all four commands can be found under the ProSteel 3D – Zoom/Views pulldown menu.

When using the above commands you are presented with a 6 pointed, 6 colored compass type screen icon. Choose the endpoint, or colored end, which is equal to the face of the plate or portion of the shape to be drilled.

In this exercise, you will add a Baseplate to to each of the columns at Gridline B, and you will drill them each with 4 holes to suit.

1. View your model isometrically, and zoom closer to the base of the left column at Gridline B.

2. Shorten each of the columns at Gridline B by 20mm. Use the “Shortens a Shape by asking for the Value” button, located on the SHAPES tab of the “Element Modification” dialog box. When prompted for the Specify

Modification Length after picking the column, enter a value of 20.

Use the “Modify 1” or “Modify 2” icons to get to the “Element Modification” dialog box, or choose “Shorten via Offset” from the ProSteel 3D /

Manipulate pulldown menu.

3. Create an Endplate as a base plate for each column. Use the values shown below, and ensure that “Without Holes” is ticked for the Drill Pattern. You can get to the “ProSteel 3D Endplate Connection” dialog box by picking the Endplate icon on the ProSteel 3D Elements toolbar, or by choosing Endplate from the ProSteel 3D / Connection pulldown menu.

As there is no Bottom Train or Stiffeners to our baseplate, then the BT.Trian, Stiffener and Stiffeners tabs are not used in this case. On the Group tab, ensure that Create Group, and With Welds cells are ticked, and do not tick any of the Safety cope cells. Leave the Assignment tab for the time being.

(71)

4. Use one of the “Object UCS” or “Object View” commands to orientate the UCS parallel to the top face of the baseplate. Remember you are choosing the plate surface where we will be drilling.

or

5. Use the “Drill” command to invoke the ProSteel 3D Bolting dialog box. Fill in the values as shown below, then select the “Insert Holes to an Object” button to execute this pattern.

and then

Now select the Object to be Drilled as prompted, (the baseplate) and then pick the Insertion Point of the Drill Pattern as prompted. In this case use the “PS Shapepoints” object snap option as an insertion point. It can be located on the “ProSteel 3D Osnap” toolbar.

(72)

D r i l l i n g P r o S t e e l 3 D 1 7

Now choose the bottom end/mid point of the column as the insertion point. You will see a yellow asterisk osnap icon showing you have found the mid point. Left click to accept the Osnap point, then click the “OK” button on the dialog box to finish the “Drill” command. You should now have a Baseplate drill pattern which looks like this:

Drill a similar pattern at both Grid B column baseplates.

6. More on drilling: The cells “Shape/X Dir” and “Cross/Y Dir” in the “Drill” dialog box define the drill hole pattern. The numerical values in front of the * indicate the number of drill holes and the spacing of the drill holes is specified behind the *. If groups of drill holes with different spaces are to be separated from one another, it is necessary to enter the corresponding value separated by a comma from the drill hole groups. Although this sounds a bit complex in theory, the practical application is quite easy. Example below:

Shape/X Dir: 2*60,200,1*,200,3*40

Chapter 09

Groups

In this chapter, you will group parts together ready for the creation of parts lists.

Objectives

Group together exi sting components at Gridline A.

Group together exi sting components at Gridline B.

Group together exi sting components at Gridline D.

(75)

Groups

We will now perform the massing of interconnected parts into groups. This is especially important for the creation of parts lists and the automatic detailing process. When you choose to perform grouping will depend on the complexity of your model, and grouping will quite often be performed more than once.

The Groups toolbar is shown below:

The Administer Groups dialog box is shown below:

ProSteel 3D creates construction groups automatically for many straightforward cases. For example, this applies for endplates, stiffeners etc. if the “Create Group” option has been ticked on the appropriate dialog box tab when creating those items.

A construction group always consists of ONE primary component, and as many secondary components as desired. Groups cannot be nested, which means that a group cannot be a secondary part of another group.

Note also that Group Selection from within ProSteel 3D can be toggled on and off with CTRL+H. This uses the AutoCAD “PICKSTYLE” command. 0 = No Group
