I have experimented a bit and looked everywhere to try to edit the elevation shape of a wall composite element, no luck so far. The beam tool sort of allows it.
Is it possible to alter the elevation shape of a composite wall into, for instance, a polygon shaped element (in elevation)? End, bottom, and/or top edges?
E.G. a 30 foot long garden wall whose top slopes down from 8 feet to 4 feet. and one end is angled at about 60 degrees?
And, while we're at it > a slab that slopes?
