Creating wall features
Once a standard round or straight wall has been created, features such as projections and recesses can be added to it. Create wall features from 2D or 3D objects, as well as symbols. By default, 2D objects are extruded to span the height of the wall, but offsets from the top and bottom of the wall can be specified. Use 3D objects, such as sweeps or other solids, to create more complicated features. Use symbols to be able to update multiple instances of a feature with a single edit.
It is not recommended to create wall features that are applied to the entire length of the wall, such as battered walls, or wall caps.
Unlike a symbol, a wall feature is actually part of the wall geometry. A wall feature interacts with the wall components, it renders along with the rest of the wall, and if it was created from a 2D object, it automatically adjusts when the wall height changes. Because wall features interact with wall components, wall features cannot be created for curtain walls.
