Use this procedure to specify the faces on object components created from extruding a profile. These objects and components include extruded mass elements, wall body modifiers, custom railing components, and other components extruded from a profile.
When you create a profile, all the edges are marked for extrusion in the Z direction. These edge positions are calculated based upon the quadrant in which the midpoint of the edge lies. You can change the view direction of edges and the extrusion direction in the profile definition.
Determine the direction of the profile edges before creating objects from the profile. For example, if you created a profile for a custom railing baluster and specified the direction of the individual edges, any baluster added to the railing based on that profile has those assignments. If you later change the edge view direction in the profile, existing balusters do not change accordingly.
The edge positions that are available depend on the extrusion direction you selected.
