You can create a quick profile based on the 3D poly, then it becomes a projection.
The quick profile isn't bad, but I'd like something more permanent.
Quick Profiles in C3D are crap... Quick Profiles in Land Desktop were just that an normal Profile generated Quickly, and were permanent.
Civil 3D should support the legacy style Quick Profile (
permanent normal Profile per default Styles, etc.), and a Quick Profile View which instead of inserting an Entity in Model Space, generates the 'Profile View' via Object Viewer.
Put simply, any entity inserted into Model Space, that can be manipulated after-the-fact should _
NOT_ be a temporary entity.
I've tried pointing this out to Autodesk, and the only feedback was (
and I paraphrase) "We designed it this way, see the help documentation."
