I've never had a problem projecting objects to a view: Blocks, points, FL.
I've not run into a need to project something that told me no way.
I still would like to understand what you would do with a projected alignemnt to a profile (sounds funny because a profile is a projected alignment)
I can't even find a simple list within Civil 3D's useless help.
-Civil 3D 2012
From C3D2012's 'useless' help under Profiles:
Looks like it includes a list of objects that can be projected.
Thank you for finding that for me. That was what I was looking for. I could go on a rant prior to 2012 I found the solution to 80% of my problems under help, and after 2012, I can't find anything.
This is from Berry's FAKS sheet. The place to look for answers involving Civil 3D is Google. Quite amazing.
