3D AutoCad File

#1
Dear IntelliCad users,
I have just started to try IntelliCad 5SE.
Could you please advise how do i open a 3D AutoCad file? Could the 5SE handle 3D drawing?
Appreciate very much for your kind assistance. Thank you.
Regards
TS

There should be nothing different from the outside between 2d and 3d files - they are all .dwg files and should open normally. Are you having trouble opening one?
