I cannot get trim to roof to work in 12. I followed the help rules, but
the command is not active in the Design/Trim to roof. I may be missing
something. RAN
Thank you for the reply. I will review solid operations. I was
attempting to work in a 3D Document instead of the 3D generic
perspective. It did not occur to me that it mattered. Sorry about the
double post. I consider this issue resolved.
