One thing that fester225 may be referring to is the way the protractor
and rotation tools need a surface to align to. I have been modelling
non-flat shapes and, like fester225, had to create a temporary cube
simply to get the required plane of rotation.
It would be nice if there was some way to tell the tool which plad to
use. How about a new command that could be entered in the dimensions
box, e.g. axisred ?
