Creating Wall Projections

1. Create the closed 2D or 3D solid object with which to modify the wall. The geometry of the object must define an area or volume that has no self-contacts, no self-intersections, and no edges that fold back on themselves.

2. For a 2D object, simply make sure that the object overlaps the wall, and that the view is Top/Plan. For a 3D object, first create the object at the appropriate height in relation to the bottom of the wall (Z axis); then set the appropriate X and Y axis location so that the object overlaps the wall.

3. With both the wall and the modifier object selected, choose the Create Wall Projection command from the appropriate menu:

The Create Wall Feature Projection dialog box opens; different fields display depending on whether a 2D or 3D modifier object was selected.

Parameter	Description
Feature Component	From the list of components currently in the wall, select a component to be applied to the area of the feature object. Otherwise, select <Object> to use the object’s own fill, or select <None> if the feature is intended to be a hole in the wall (for example, to create an opening for an object that is not part of the wall).
Left Side Wrap (2D objects only)	Select the first component to wrap around the feature on the left side of the wall; this can be <None>, or any component to the left of the Feature Component (higher in the list). All components to the outside of the Left Side Wrap component also wrap.
Right Side Wrap (2D objects only)	Select the first component to wrap around the feature on the right side of the wall; this can be <None>, or any component to the right of the Feature Component (lower in the list). All components to the outside of the Right Side Wrap component also wrap.
Offset From Wall Top (2D objects only)	Specifies the distance from the top of the wall where the wall feature ends in 3D views
Use Profile as Core (2D objects only)	Select this option to use the area of the original 2D object as the core of the wall feature; other wall components will wrap around the core, which may make the projection larger than the original object. Deselect this option to limit the area of the projection to the area of the original 2D object.
Cut Plane (3D objects only)	Specifies the distance from the bottom of the wall at which a section slice is taken of the 3D object and is used to represent the wall feature in Top/Plan view. If the 3D object does not run the whole height of the wall, be sure that this value actually intersects the 3D object; otherwise the object will not appear in Top/Plan view.
Use Object 3D Attributes (3D objects only)	Select this option to display the surfaces created by the feature object with its own attributes when it is rendered in 3D; when deselected, the wall’s attributes are used on those surfaces
Show Extents Below/Above Cut Plane (3D objects only)	In addition to the 3D section specified by the Cut Plane value, shows the outline of the part of the 3D object below and above the cut plane; the pen attributes of this representation can be edited (see Wall Feature Properties)
Preview	Changes the view of the wall feature to match the current parameter settings, without saving the settings
