154 Structure User's Guide If the start and end points are aligned on the same parallel vector, then the minimum distance
is 1 cm.
If you import grid lines into the 2-D environment as references and then sketch a wall path on top of the grid lines, the software will create horizontal or vertical constraints to the grid lines.
You can select multiple wall parts or wall systems as a group and edit properties either in the ribbon bar or in the property pages .The limitations when editing multiple walls are that you cannot modify support, path or boundaries values.
Place Wall Ribbon
Specifies the properties for the wall(s) that you are placing or editing. If you select multiple walls to edit, the values that are the same for the selected walls are displayed. If a value is different between the selected walls, the value is not shown.
If you have multiple walls selected and you enter a new value in the ribbon, it is applied to ALL selected walls.
Wall Properties - Activates the Wall Properties dialog box. You can use this dialog box to specify additional wall properties, such as material and material grade, which you cannot set on the ribbon. For more information, see Wall System Properties Dialog Box (on page 165).
Sketching Plane, Select a Path and Select Boundaries are unavailable and cannot be edited when multiple walls are selected.
Sketching Plane - Select the support plane for the bottom of the wall.
Select a Path - Select the Sketch 2D or Sketch 3D option.
Select Boundaries - Select additional graphic objects to be boundaries for the wall. You can select members, other walls, grid planes, and surfaces. An example of when to use this option would be when placing a wall under a pitched roof.
Finish - Places the wall using the defined parameters.
Cancel - Clears all selected planes or boundary objects.
Accept - Accepts all selected planes or boundary objects.
Sketch 2D - Opens the sketch 2-D environment in which you can draw the path of the wall.
You can draw more than one wall at a time in the 2-D environment. However, if you draw more than one wall path in the 2-D environment, the walls will move as a single unit if you move any of the walls regardless of whether or not the walls are connected to each other. If you will need to move any of the walls individually, you must draw that wall's path in 2-D environment by itself.
For slabs and walls defined in the sketch 2-D environment, SmartPlant 3D removes any constraints external to the defining group when you:
Copy a slab or wall. The original slab or wall will still have the constraints, however the newly created copy of the slab or wall will not have the external constraints.
Structure User's Guide 155
Move a slab or wall. All external constraints are removed from the slab or wall.
Rotate a slab or wall. All external constraints are removed from the slab or wall.
The defining group is the lines (or other shapes) that you place in the sketch 2-D environment that define the actual slab or wall. An example of an external to the group constraint might be an edge of a Slab XZY offset from the edge of Slab 123. The constraint is between two different slabs (defined by two different groups) so it is removed. An example of an internal to the group constraint that is not removed might be one slab side constrained to be parallel to the opposite side. In this case both sides belong to the same slab, and hence the same group, and the constraint is therefore not removed.
Sketch 3D - Activates the Create Path Ribbon with which you define the wall path. Select this option to sketch the path of the wall in the 3-D environment.
System - Select the parent system for the wall that you are placing. Systems are defined using the Systems and Specifications task.
Type - Select the type of wall to place. The properties change depending on the wall type that you select.
Composition - Select a wall composition from the list. Available compositions depend on the type of wall being placed.
Name - Displays the name of the wall that you are placing.
Position - Specify the relative position of the wall to the path. Fifteen positions are available. The location of positions 10 (center-of-gravity) and 15 (shear center) depend on the wall's section shape. The local z- axis of the wall and the center-of-gravity point of the section define positions 11 and 14. The local y-axis of the wall and the center-of-gravity point of the section define positions 12 and 13.
Total Thickness - Type the thickness of the wall. The default thickness is based on the selected wall type and composition.
If the wall has more than one layer, then the Total Thickness box is read-only. To edit the wall thickness, use the Layer tab of the Wall Properties dialog box. For more information, see Edit Wall Properties (on page 164).
Maximum Height - Enter the maximum height for the wall.
Reflect - Reflects or mirrors the cross-section about the wall's path. This parameter affects both symmetric and asymmetric sections.
