Introduction
LiteCAD
The availability of low cost CAD software has radically changed the way professionals work. Most project managers now expect that CAD software will be used to create digital drawings describing design work. Managers and clients also assume that design work will be delivered in both printed and electronic format. So, in most professions, producing design work on paper drawings alone is no longer acceptable; you need CAD. This change in attitude has major implications for many of us. If you are working, or intend to work, in the Architecture, Engineering or Construction industry, you need to be able to produce CAD drawings if required. It goes without saying that you need to learn to do this efficiently, making the CAD software work hard for you, not the other way around.
CAD drawings are full size
It is worth making the point that everything you draw with your CAD software must be drawn full size. This means that if any time you make an inquiry of any part of your drawing (using any of the inquiry commands in Tools - DISTANCE or AREA) the software 'spits back' values on the Command line (and in the a
properties dialog box) which mean something to you as a designer. If objects you design fit when working in the CAD model, they will fit in real life. This concept of 'drawing full size', is a major change for many people and can be most disconcerting, if you have long been used to producing paper drawings by hand.
About LiteCAD
LiteCAD is a product of Design Cad Pty Ltd, a software company based in Adelaide, South Australia. LiteCAD commands and AutoCAD
LiteCAD is largely command compatible with AutoCAD, industry standard CAD software. If you know how to use AutoCAD, you will feel right at home with LiteCAD. If not, help is available on LiteCAD's web site (http:// www.plus.designcad.com.au). There you will find many short on-screen movies to help you learn to use the software.

System requirements
System requirements - LiteCAD under Windows
LiteCAD and the applications based on it, will run on most Windows computers. We have tested the software under various operating systems - Windows XP, Windows 2000, Windows 7 and Windows 8. A reasonable specification for a computer running LiteCAD would be one with an Intel i5 processor, 4 GIG of RAM and at least 250 GIG of storage space. LiteCAD will also run on computers using other chips, but has not been exhaustively tested.
Requirements - LiteCAD on Macintosh computers
LiteCAD software was originally designed for Windows computers, but can run on Macintosh computers provided that the processor is Intel based and some form of Windows emulator runs concomitantly with LiteCAD. Most recent Mac computers (post 2006) are Intel based and a Mac computer with an i5 processor 4-8 MB of hard disk space should be adequate to run LiteCAD.
There are a couple of extra items required to run LiteCAD successfully on a Mac:
1. You need to purchase a mouse with more than one button and a wheel to drive LiteCAD effectively on a Mac. The reason for this is that when using LiteCAD, different menus pop up when either the left or right mouse button is clicked and the mouse wheel is used to zoom in and out on the drawing. Trying to use LiteCAD with the traditional single button Mac mouse is very frustrating indeed. Apple now offer a range of mice and track pads with various buttons, but we find that Logitech mice with a central wheel and plugged into the USB port of our iMac work well.
2. You also need to install a special piece of emulator software that allows Windows programs to run on the Mac. We are aware of a number of such programs and have tested Crossover (R) and Parallels (R). These both seem to work satisfactorily. Crossover seems to be the favorite among Mac LiteCAD users, but we use Parallels on our iMac. We recommend adding extra RAM to help the Mac performance. One of these emulator tools needs to be installed before installing LiteCAD. We do not recommend booting into a Windows environment to run LiteCAD as you lose all the great features of the Mac.
Note that you need a separate Windows license to run Parallels.

What's new
What's new
Recent changes made to LiteCAD are listed here:
Installing LiteCAD
Installing LiteCAD
LiteCAD runs in both the Windows and Macintosh environments. The software is not 'memory hungry' and will run on modestly powered computers. We have tested it on various operating systems - Windows XP, Windows 2000, Windows 7 and Windows 8. A reasonable specification for a computer running LiteCAD would be an i5 processor, 4Gig of RAM and 150 Gig of storage space.
The pages linked here provide specific information on installing LiteCAD in each environment. Created with the Personal Edition of HelpNDoc: Easily create Web Help sites
Windows
LiteCAD Windows installation
The download delivers a single installation file (which will have a file name similar to LiteCAD_Setup.exe). We suggest saving the file to your desk top. Check the file size by selecting the icon and right clicking. The file should be nearly 13 Megabytes in size; if it is less, there is a chance that the download is incomplete. To install the program, start Windows Explorer or the Your Computer tool, go to the desk top and locate the LiteCAD setup file and double click on it, accept our license agreement (which basically says that you will use the program on one computer only, and not give away copies of the program) and LiteCAD will be installed. Start the program by clicking on the desktop shortcut.

Apple Mac
LiteCAD on Macintosh computers
LiteCAD software was originally designed for Windows computers, but can run happily on Macintosh computers provided that the processor is Intel based, and you run some form of Windows emulator. Most recent Mac computers (purchased post 2006) are Intel based and a free version of the emulator is available to test with (free) LiteCAD Lite before buying LiteCAD.
Extras
There are a couple of extra items required to run LiteCAD successfully on a Mac:
1. In our view, to drive LiteCAD effectively on a Mac, you need to a mouse with more than one button. The reason for this is that when using LiteCAD, different menus pop up when either the left or right mouse button is clicked. In addition, the mouse wheel (or gesture on the Mac Magic Mouse) is used to zoom in and out on a drawing. Trying to use LiteCAD with the traditional single button Mac mouse is very
frustrating indeed.
Apple now offer a range of mice and track pads with various buttons. We have used the Mac Magic Mouse/ LiteCAD combination, but lean towards using an easily available LogiTech mouse that we plug into a USB port on our Mac. We have not had much success with our Apple Track Pad, but that may be because we have not experimented with the many ways to activate buttons and gestures.
2. You also need to install a special piece of software that allows Windows programs such as LiteCAD to run on the Mac. We are aware of a number of such programs - BootCamp [free with your Mac],
Crossover - a Virtual Windows Emulator [free to try and costing around $USD40.00 for the standard version] Parallels Desktop [approx $90.00), Wine [free, but quite tricky to set up] and VMWare Fusion [about $50.00]), all seem to work satisfactorily with LiteCAD. Crossover seems to be the favorite among LiteCAD users on Mac, as it is possible to download a trial version of LiteCAD Lite and a trial version of
Crossover and test things out, before purchasing either Crossover or LiteCAD. You also need a
Windows license to make LiteCAD work with Boot Camp, Parallels Desktop and VM Fusion. If you don't have one, that adds extra expense.
One of these tools needs to be installed before installing LiteCAD.
Installing LiteCAD after Crossover has been downloaded
1. Download the Exe file and save to your desktop. 2. Launch CrossOver from your OS Applications menu. 3. Choose Install Windows Software.
4. Scroll down the Supported Applications list and choose Select Other Application [Under Community Supported Applications]
5. Select Choose Installer file, select the downloaded Exe file on your desktop.
6. Follow the On-screen prompts and install. Note that although LiteCAD may install and run, complete installation may take some time.
Once you have LiteCAD working, if you use the File>Open sequence, you can 'play' with several landscape sample files. More designs are available for download from this web site. Links to sample files using feet and inches as the base unit are available from the USA drop down menu on this site.
Test LiteCAD
Please test your installation. We have provided several sample drawings for you to experiment with. These are stored in the Jobs folder. Simply use File>Open. If these drawings load and display correctly, then your copy of LiteCAD is ready for work!
Note that if you install LiteCAD under Crossover, the path to the Jobs folder is quite long viz.

File menu
File drop down menu
This menu contains most of the features you would expect to find in this position in modern software. Options here allow starting a new design, printing a drawing, close a drawing, save a copy of a drawing, opening an existing drawing, accessing recent files etc.
New
Selecting this option leads to a template folder. A range of templates are available for different size spaces and purposes; all are preloaded plant symbols and some containing design work.
Open
Here you are taken to the folder previously used to find a drawing. The 'Recent' options and its icon on the standard toolbar shows a list of drawings recently worked on. These may come from different folders. Insert
This command as the name implies, inserts a LiteCAD drawing into the current drawing space. unlike the BLOCK or BLOCKS commands, there is no opportunity to scale or change the rotation angle of the entities being imported. Again, unlike a block, all entities are exploded on entry using this option.
Save
Saves a copy of the drawing. SaveAs
Allows a drawing to be saved in lcd, dwg or dxf format. A text file option is also available. It has little value at present, but we will use it for future development.
Note: When LiteCAD saves and closes a drawing, a backup copy of the file is saved with the extension .bak
while the new drawing has the extension .lcd (LiteCAD native file format) or dwg (AutoCAD format). As an additional safeguard, every 15 minutes while you are drafting, LiteCAD saves a further copy of the drawing with the extension .lc$ or .dw$. Both the backup and AutoSave files need to be renamed (we suggest to a name such as Recovered.lcd) in order to be worked on.
Calls up the Print dialog box. Here you can select a printer (the size of paper on which to print), centre the print, preview the print etc. We recommend installing a PDF writer such as CutePDF (free) and printing to
PDF wherever possible. Exit

View menu
View drop down menu
This menu contains links to commands that enable drawings to be viewed in different ways. Zoom Extents
This option will show the whole drawing displayed at its maximum size. Zoom Limits
it is possible (via the Tools drop down menu to constrain the drawing to a certain area - the drawing limits). This option will zoom the view to those limits
Zoom Window
Draw a box and zoom to that area. Zoom Previous
Go back to the previously zoomed view. Zoom Selected
Pick an entity in the drawing and zoom in on it. Regen
Refreshes the screen. Sometimes needed if zoom extents does not show the whole drawing. Pan
Real time Pan Properties
Toggle the display of the Properties box on or off. Command Line
Toggle the display of the Command area box on or off. Toolbars
Customize the icons on the toolbars to your own liking.
Format menu
Format drop down menu
This menu contains links to commands that enable changes in the way you work with a drawing - change text styles, dimension styles, linetypes, layers, deal with blocks etc.
Layers
This tool enables users to create new layers, control the colour, linetype, line thickness of layers. If you want to change the stacking order of entities on a layer see the Tools menu.
Linetypes
A linetype defines a line's characteristics. A line can consist of combinations of dashes, dots, spaces and symbols. New entities are added to a drawing using the current linetype. When you create a new drawing it already has linetypes named "ByLayer", "ByBlock", and, "Continuous".
The LINETYPE command shows the dialog box below. LiteCAD allows the use of AutoCAD .lin files. These can be loaded using the 'add from file' option in this dialog box.
Line weight
Lineweights add width to your objects, both on screen and on paper. Using lineweights, you can create heavy and thin lines and vary object thicknesses in details. Just as heavy and thin lead weights are used in manual drafting, lineweights can be used to graphically represent different objects and types of information. The figure below shows a thicker line being applied to the walls and thinner line thicknesses to other entities.
You should not use lineweights, however, to represent the exact width of an object. For example, if you want to draw an object with a real-world width of 1.5 millimeters, you should not use a lineweight; instead, use a polyline with a width of 1.5 millimeters to represent the object accurately.
Lineweights are displayed differently in model space than in a paper space layout. In model space, lineweights are displayed in relation to pixels. In a paper space layout, lineweights display in the exact plotting width. Lineweights should be used for the graphic representation of different objects and types of information, and are, therefore, displayed in model space in proportional pixel values. You can recognize that an object has a thick or thin lineweight in model space but the lineweight does not represent an object's real-world width. A lineweight value of 0 is displayed as one pixel in model space and print at the thinnest lineweight available on the specified printer. All other lineweights are displayed using a pixel width in proportion to its real-world unit value.
Lineweight display in model space does not change with the zoom factor. For example, a lineweight value that is represented by a width of four pixels is always displayed using four pixels regardless of how far you zoom into your drawing.
You can set the display scale of lineweights if you want the lineweights on objects to appear thicker or thinner at model space. Changing the display scale does not affect the lineweight plotting value. However, a drawing's redraw time increases with lineweights that are represented by more than one pixel.
Colours
All colors used in LiteCAD are stored in a table called the "Color palette". Each color of the palette is an RGB value. The palette can be loaded and saved to/from disk file. The Color value of a LiteCAD object is an index value of the palette. An entity uses an index value ranging from 1 to 255 or the color is specified "ByLayer" or "ByBlock".
layer. "ByBlock" means the color assigned to a Block will dictate the color of an entity added to a Block Insertion entity. If the entity is not a part of block but has the "ByBlock" color assigned to it, the white color (7) will be used to draw the entity.
Custom colors can also be added via the Options tool.
Text Styles
A wide range of text styles can be created. We favour the use of hand written styles. a number of these are pre-loaded in templates.
Point styles
A point is a single entity with a fixed coordinate position.This command enables users to change the appearance of the point style marker.
Dimension Styles
Dimensions can be taken automatically from the model. This option allows users to set up personalized dimension styles, modifying such things as arrow heard type, text style, offsets from model etc.
Multiline Styles
It is possible to draw complex commands after a style has been set up. A multiline style might be used to draw a double brick wall.
Images
Calls the Image manager where images can be attached to or detached from the drawing. Layouts
This option is used to set up layouts - views of the design or parts of the design on drawing sheets. Units
LiteCAD drawings are full size. This option allows you to set up your usual drawing units for scaling insertion of objects (mm or decimal feet being the most common), rotation angle, desired precision etc.
Limits
Adjust the area available for drawing. Block
Used to make a block (collection of entities grouped together). Identify a base point and provide a description.
Blocks
Review (browse) blocks associated with a drawing. Search for blocks outside the current drawing and insert into the current space if required.

Dimension Dimensions
Dimensions show the measurements of objects, the distances or angles between objects, or the distance of a feature from an origin you specify. LiteCAD provides three basic types of dimensioning: linear, radial, and angular. Dimensions can be horizontal, vertical, aligned, rotated, ordinate.
You can dimension objects, such as lines, arcs, circles, and polyline segments, or you can dimension
between point locations. LiteCAD places dimensions on the current layer. Every dimension assumes the current dimension style, which controls characteristics such as arrowhead style, text location, units format, etc. With dimension styles, you can make subtle modifications to a base dimension style for different types of dimensions.

Viewing drawings
Viewing drawings
Once a reasonable number of elements have been placed into a drawing, it becomes necessary to learn to efficiently move the drawing (called PANning) and to obtain closer view of some parts of the drawing (this is called ZOOMing in). Zooming (and panning) a drawing are techniques that you do need to master quite early on in your CAD learning in order to work effectively with CAD. All of these operations can be carried out with the aid of a mouse, however, all options are replicated on the View drop down menu.

Moving around
Moving around inside the drawing editor
The mouse wheel can be used to Zoom in and out
Position the mouse pointer (or cross hairs) over an area of interest. Roll the wheel of the mouse away from you to zoom in and away from you to zoom out. Double click the wheel of the mouse to see the complete drawing (zoom extents). Horizontal and vertical scroll bars will automatically appear when zoomed in. Using the mouse to pan a drawing
Position the mouse over an area of interest. Press and hold the mouse wheel while dragging to move the drawing - it's rather like moving a paper drawing sheet across the desk.

Magnify and shrink drawings Magnify and shrink a view
The ZOOM command is use to control the magnification of any part of a drawing. Zoom can be carried out (started) by typing the command (word) ZOOM in the command area and pressing the <ENTER> key. Either lowercase or uppercase may be used.
Type ZOOM (or Z) and press <ENTER>.
The following message will appear in the Command area. All/Center/Dynamic/Extents/Left/Previous/<Scale>(X)>: The Command line options are:
[All/Center/Dynamic/Extents/Left/Previous/<Scale>(X)>]
To choose the Window option - i.e. type W and press <RETURN>.
After typing W, you will then be asked to nominate the corner of that part of the drawing that you wish to magnify.
To Zoom into an area, indicate the bottom left hand corner of the zoom window by moving the cursor (moving cross-hairs) to that position. Now set the top right hand corner to totally enclose any part of the drawing. You will see a box 'rubber banding' from the bottom left as you do this. When you set the right hand side of the window with the pick button, the drawing will automatically be magnified. The area previously inside the
zoom box now occupies the whole screen.

Control visual elements
Controlling the visibility of an element
Layers can be used to control entity visibility. Once an entity has been placed on its own layer, the layer visibility can be turned on or off. If needs be, the layer can be locked so that there can be no inadvertent movement of entities on it. The colour of entities can be assigned BYLAYER.

Regen
Redrawing and regenerating a drawing
As you work on a drawing, visual elements may remain after the completion of a command. You can remove these elements by refreshing, or redrawing, the display.
To redraw (refresh) the current window display
Do one of the following:
·
Choose View > Regenerate·
Type regen and then press Enter. The phrase "regenerating the model" will show in the command area.Information about drawing entities is stored in a database as floating point values, ensuring a high level of precision. Sometimes a drawing must be recalculated, or regenerated, from the floating-point database to convert those values to the appropriate screen coordinates. This occurs automatically.

Layers Layers
A layer is a logical grouping of data, assembled as though they were laid out on transparent acetate overlays.
To manage layers
Do one of the following:
1. Choose Layers .. from the Format drop down menu. 2. Type LAYER in the command line and then press Enter.
Select current layer
Click on the black down indicator in the group showing the light bulb icon and select the required layer name. The light bulb turns a layer on or off, the lock icon locks a layer preventing editing, the printer icon controls whether or not entities on a layer print or not and the small block indicates the current colour of the layer.
Features
Users may choose to put certain types of entities on certain layers. Layers can be turned off and on, so that their respective data can be viewed in or out of context with adjacent layers. Note that all new graphic
objects are added to the current layer.
When a new drawing is created, it will already have one layer named "0" [layer zero].

Line
Line command
A line consists of two points: a start point and an endpoint. A series of lines can be connected, but each line segment is considered a separate line entity.
To draw a line
1.
Do one of the following:·
Choose Draw > Line from the Draw drop down menu.·
On a toolbar, click the Line tool.·
Type line and then press Enter.·
Type L and press Enter2.
Specify the start point.3.
Specify the endpoint.4.
Hit enter or right click to finish. Coordinate entryYou can input coordinates in the command line with the same way as in AutoCAD:
To use a coordinate to specify a point, enter an X value and a Y value separated by a comma (X,Y). To specify a relative coordinate, precede the coordinate with an @ symbol.
For example, the coordinate @3,4 specifies a point 3 units along the X axis and 4 units along the Y axis from the last point specified.
To enter a polar coordinate, enter a distance and an angle separated by an angle bracket (<).
For example, to specify a point that is at a distance of 1 unit from the previous point and at an angle of 45 degrees, enter @1<45.
By default, angles increase in the counterclockwise direction and decrease in the clockwise direction. To move clockwise, enter a negative value for the angle. For example, entering 1<315 is the same as
entering 1<-45.
Polar coordinates are either absolute (measured from the origin) or relative to the previous point. To specify a relative coordinate, precede the coordinate with an @ symbol.

Point Point
A point is a marker that can appear as a dot, square, circle, X, or plus sign (+), or as a block insertion with applied text. The point's appearance depends on the assigned Point Style. Points can act as nodes to which you can snap objects. Points are also visible within the viewport, regardless of how small or large the viewport scale may be. This makes points a valuable tool in the construction of CAD based maps.
A point is a single entity in a LiteCAD drawing. A point is known as a node and it is possible to 'osnap' to a point. The size if the point marker can be controlled by defining a new point style (see Format>point Styles). To draw a point
1.
Do one of the following:·
Choose Draw > Point.·
On a toolbar, click the Point tool.·
Type Point or PO and then press Enter.A point entity is placed at the insertion coordinate. The POINTSTYLE command enables users to set up a variety of different point markers.

Text Text
Text conveys important information in your drawing. You use text for title blocks, to label parts of the drawing, to give specifications, or to make annotations. Text is created using the current text style. LiteCAD allows the following types of text entry:
·
Single line text·
Multiline text·
Windows textCreated with the Personal Edition of HelpNDoc: Create iPhone web-based documentation Single line
Text
Single-line text is an individual line of text contained in one text object. It is useful for labels and short notes. If you have longer notes that may exceed one line, use paragraph text. The insertion point is a Point object indicating the coordinate location for placing the text. The text height is a real number defining the height of the upper-case characters in drawing units.
When you create text, you end each line of text by pressing Enter. Each line of text is created as a separate entity that you can modify.

Multiline or Paragraph text
Paragraph text consists of one or more lines of text or paragraphs that fit within a boundary width that you specify. Each paragraph text entity you create is treated as a single entity regardless of the number of individual paragraphs or lines of text it contains.
When you create paragraph text, you first determine the paragraph's boundary width by specifying the opposite corners of a rectangle. The paragraph text automatically wraps so that it fits within this rectangle. The first corner of the rectangle determines the default attachment point of the paragraph text. You can change the location of the attachment point in reference to the rectangle, and you can also determine the direction in which text flows within the rectangle. It is also possible to select the text and paragraph format, text style, text height, and the rotation angle of the entire paragraph text entity.

Create Block Blocks
LiteCAD is designed to enable the production of accurate Computer Aided Design (CAD) landscape plans quickly. To that end, we have provided a library of previously drawn plant symbols to assist you, but you can make your own. These symbols whether they be ours or yours can be placed (stamped) into the drawing space as often as required. Blocks are made with the BLOCK command.
To create a block
1.
Do one of the following:·
Choose Draw > Create Block from the Draw drop down menu.·
On a toolbar, click the Create Block tool.·
Type BLOCK or B in the command line and then press Enter. Note:Each block symbol can consist of elements on different layers. This enables the production of several plans from the one drawing, just by a mouse click, turning layers on and off as needed. Reusable symbols are of great value when it comes to details that normally accompany landscape drawings.

Hatch Hatch
Hatch allows inserting hatch patterns such as brick, paving or decking inside closed drawing forms such as circles, squares, rectangles, triangles or more complex (and closed) shapes using spline or polylines. Tip - For this command to work you must have a closed element to work with. Try starting with a simple circle or rectangle to understand how the command works.
To apply a hatch pattern
1.
Do one of the following:·
Choose Draw > Create Hatch from the Draw drop down menu.·
On a toolbar, click the Create Hatch tool.·
Type HATCH or HA in the command line and then press Enter.From the hatch pop-up select the hatch pattern from the pattern field. If you're not sure what you want then use the drop down to pick one and you'll see it in the preview screen. While the Pattern field is blue you can use the up and down arrows on your keyboard of the center role wheel of your mouse to scroll through what you want. When you've found the appropriate pattern and before confirming you may need to alter the scale. You may need to experiment with this as it depends on how you've done your drawing. The larger the scale values the bigger the hatch pattern. You can also change the hatch angle; this is useful for paving or brickwork. Once the hatch values are set you then need to select the object in which you wish to insert the pattern.
If you are inserting into a closed entity made of a single perimeter such as a circle, ellipse, rectangle or closed polyline then use the Pick Points. The cursor will appear with a hatch pattern. You now select inside perimeter of the element you wish to fill and it will turn pink. Perform a single right mouse click and select OK
If you have a drawing that has a closed space made up from separate touching sections (e.g. a square made of 4 separate lines with all corners touching.) you need to select Pick Entities. The cursor will appear with a hatch pattern. You now select all the individual sides of the shape you wish to fill. Perform a single right mouse click and select OK.
Tip - If when using Pick Entities and the hatching does not appear, you may have a gap in the perimeter. To check zoom in and verify that each entity of the shape touches or is linked and the shape is completely closed. For complex shapes using the polylines can help. To close gaps try the Explode command – See Modify/Explode

Define attributes Attributes
An attribute is a label or tag that attaches data to a block. Examples of data that might be contained in an attribute are part numbers, prices, comments, and owners' names. The tag is equivalent to a column name in a database table. Attribute information extracted from a drawing can be used in a spreadsheet or database to produce a parts list or a bill of materials. You can associate more than one attribute with a block, provided that each attribute has a different tag. Whenever you insert a block that has a variable attribute, LiteCAD assign default value for the attributes. Later users can change the attribute value with the "Edit Block Attribute" dialog or "Properties" window.
Attributes also can be "invisible". An invisible attribute is not displayed or plotted; however, the attribute information is stored in the drawing file and can be written to an extraction file for use in a database program.
To create an attribute, you first create an attribute definition, which describes the characteristics of the attribute. The characteristics include the tag (which is a name that identifies the attribute), the prompt displayed when you insert the block, value information, text formatting, location, and any optional modes
(Invisible, Constant, and Preset).
After creating the attribute definition, you select it as one of the objects when you define the block. Then, after you insert the block, you can edit the attributes values with the "Edit Block Attribute" dialog or "Properties" window.
To use several attributes together, define them and then include them in the same block. For example, you can define attributes tagged "Parts," "Materials," and "Thickness," and then include them in a block called PARTS_DATA.

Working with coordinates
A variety of precision tools are available to help you produce quick, accurate drawings without performing tedious calculations. Although all your work is based on a coordinate system, you can establish settings that cause you to snap to locations on the screen, to specified locations on objects, or to points relative to other locations or objects.
Created with the Personal Edition of HelpNDoc: Create iPhone web-based documentation
Entering coordinates Enter coordinate values
In LiteCAD, when a command prompts you for a point, you can use the pointing device (your mouse) to specify a point by clicking, or you can enter a coordinate value on the command line. You can enter coordinates as either Cartesian or polar coordinates.
A Cartesian coordinate system has three axes, X, Y, and Z. When you enter coordinate values, you indicate a point's distance (in units) and its direction (+ or -) along the X, Y, and Z axes relative to the coordinate system's point of origin where all coordinate values are zero (0,0,0). Negative values on the X plane are left of the point of origin, and positive values on the X plane are to the right of the point of origin. Negative values on
the Y plane are below the point of origin and positive values on the Y plane are above it. Visualize the Nadir viewpoint and positive values for the Z plane indicate an elevation while negative values in the Z plane indicate a depression, or a point beyond the point of origin.
Polar coordinates use a distance and a fixed angle to locate a point. With both Cartesian and polar coordinates, you can enter absolute coordinates based on the point of origin (0,0,0), or relative coordinates based on the last point specified.
Entering Cartesian Coordinates
To use a coordinate to specify a point, enter an X value and a Y value separated by a comma (X,Y). If using the 3rd dimension, add a value for the Z plane as well... ergo the coordinate set will appear as: (X,Y,Z). The X value is the positive or negative distance, in units, along the horizontal axis. The Y value is the positive or negative distance, in units, along the vertical axis. The Z value is the positive or negative distance, in units, along the elevation-depth axis. The remaining portion of this topic deals only with two dimensions, but the Z coordinate is applicable as desired.
Absolute coordinate values are based on the origin (0,0), where the X and Y axes intersect. Use an absolute coordinate when you know the precise X and Y values of the point coordinate. For example, the coordinate 3,4 specifies a point 3 units along the X axis and 4 units along the Y axis from the origin.
Relative coordinate values are based on the last point entered. Use a relative coordinate when you know the position of a point in relation to the previous point. To specify a relative coordinate, precede the coordinate with an @ symbol. For example, the coordinate @3,4 specifies a point 3 units along the X axis and 4 units along the Y axis from the last point specified.
The following example draws a line beginning at a point with an X value of -2, a Y value of 1, and an endpoint at 3,4. Pressing ENTER at the To Point prompt ends the command.
The following example draws a line whose endpoint is 5 units in the X direction and 0 units in the Y direction from the start point at the absolute coordinate -2,1. Pressing ENTER at the next To Point prompt ends the command.
Entering Polar Coordinates
To enter a polar coordinate, enter a distance and an angle separated by an angle bracket (<). For example, to specify a point that is at a distance of 1 unit from the previous point and at an angle of 45 degrees, enter @1<45.
By default, angles increase in the counterclockwise direction and decrease in the clockwise direction. To move clockwise, enter a negative value for the angle. For example, entering 1<315 is the same as entering 1<-45.
Polar coordinates are either absolute (measured from the origin) or relative to the previous point. To specify a relative coordinate, precede the coordinate with an @ symbol.
The following example shows a line drawn with polar coordinates using the default angle direction setting. Pressing ENTER at the Next To Point prompt ends the command.
The following example shows a line drawn with relative polar coordinates. Pressing ENTER at the Next To Point prompt ends the command.
Also you can specify direction angle by mouse position relative to last entered point. At this case you specify only distance value in the command line and LiteCAD will use the coordinates of the point which are placed at specified distance from last entered point along a direction to cursor position.

Dimensioning
Dimensioning
One of the most important and often under-rated aspects of any CAD program such as LiteCAD is the ability of the software to place appropriate dimensioning into the drawing so that the design may be built. The LiteCAD program creates a database when the drawing is produced, and it accesses this database to obtain the dimensional data to be added to the drawing.
Just as accuracy is important when creating a drawing, it is also important when adding dimensions. There is no point in drawing accurately and then adding incorrect dimensions. Care must be taken, and osnaps (entity snaps) should be used where appropriate.
If you always draw full size then you can (and should) let LiteCAD take its dimensioning directly from the model that you have constructed.The movie below provides an overview of dimensioning in the LiteCAD environment.
Dimensions
Dimensions show the measurements of objects, the distances or angles between objects, or the distance of a feature from an origin you specify. LiteCAD provides three basic types of dimensioning: linear, radial, and angular. Dimensions can be horizontal, vertical, aligned, rotated, ordinate. Some simple examples are shown in the illustration below.
You can dimension objects, such as lines, arcs, circles, and polyline segments, or you can dimension
between point locations. LiteCAD places dimensions on the current layer. Every dimension assumes the current dimension style, which controls characteristics such as arrowhead style, text location, units format, etc. With dimension styles, you can make subtle modifications to a base dimension style for different types of dimensions.

Create dimension
Dimension drop down menu
This menu contains links to all the commands that enable the placement of dimensions into a drawing. Create a new dimension style from the Format drop down menu.
You can use control codes to add special characters, such as tolerance or dimensioning symbols.
Control code Result
%%d Degree symbol (°)
%%p Tolerance symbol (±)
%%c Diameter symbol (Ø)
You can also enter any character by its Unicode value, with the control code \U+xxxx, where xxxx is the hexadecimal value of the Unicode character. For example:
Control code Result
\U+00B0 Degree symbol (°) \U+00B1 Tolerance symbol (±) \U+2205 Diameter symbol (Ø)
\U+20AC Euro symbol (€)
\U+00A9 Copyright symbol (©)
The character must exist in a font file, otherwise LiteCAD will draw an empty rectangle instead of this character.
You can view all available characters in LiteCAD fonts and their Unicode values with the dialog "Installed LiteCAD Fonts".

Linear
Linear dimensioning
One of the most important and often under-rated aspects of a vector based CAD program such as LiteCAD is the ability of the software to place appropriate dimensioning into the drawing so that the design may be built. The LiteCAD program creates a database when the drawing is produced, and it can access this database to obtain dimensional data to be added to the drawing. The dimension is taken from the full size model. Just as accuracy is important when creating a drawing, it is also important when adding dimensions to a drawing. There is no point in drawing accurately and then adding incorrect dimensions. Care must be taken, and osnaps should be used where appropriate.

Edit dimension Editing a dimension
The whole idea of dimensioning is to have the software take a dimension from a CAD model. Since the model reflect the measurements in the real world that will be applied when the design is constructed, applying a dimension provides a real check on the accuracy of your CAD work.
There are times when a dimension needs to be altered and dimensions can be edited. This is best done by applying a new dimension style to an existing dimension.
BUT BE CAREFUL. We think that it is better practice to delete the dimension and reapply it

From Model Space
While you will do most of your design work in model space, LiteCAD offers a space for presenting many views of the design on any size sheet required. In other words, LiteCAD drawings can contain more than one layout page.
The first page seen when you start LiteCAD, represents the "Model Space" and is used to create the main drawing (using the the drawing editor). When you create a new drawing, that space is already there. When
added, additional layout pages are added, these represent two-dimensional paper sheets used to compose or lay out your model drawing for printing. These may consist of a title block, one or more view ports, and annotations.
Created with the Personal Edition of HelpNDoc: Easy CHM and documentation editor
From Layout Layout
Use Format.Layout to create a new layout sheet. Choose an appropriate paper size for your presentation. The layout (or paper space) feature offers many avenues for creative and effective communication of your design ideas. At first glance, using paper space appears complex, especially if you have long been used to working entirely in tiled model space.
Rule 1:
Draw your design in tiled model space at full size. Various parts of the drawing can be placed anywhere in the drawing space that you want. If necessary when the drawing covers a large area such as a road, use named views to move smoothly around in model space.
Rule 2:
When dimensioning, create all dimensioning in tiled model space and not paper space.
Since the intention is that parts of the design will be displayed in paper space at different scales, differing dimension settings will be needed on each part of the design. Dimensioning arrow heads and text sizes need to be consistent across the final presentation sheet (in paper space).
Rule 3
Create a master dimensioning style named DIM-XXX where XXX is the largest scale to be used in the drawing.
Use dimension styles to cope with the need to have an arrow head sizes and text heights appropriate for each floating view port.
A typical set of named dimension styles for architectural use is shown below:
100 (parent), 100$7 (child – leader with solid arrow rather than angled tick), 5, 5$7, DIM-50, DIM-50$7
Rule 4:
Place text describing the part (E.g. PLAN, SECTION A-A) in model space rather than paper space.
