Duh!
I discovered my errors of yesterday. I tested the copy/paste functions in R5 by placing a small box in an existing drawing and
then copy/pasting it. When I copy/pasted into MoI it came in way, way off screen and though I did zoom out to find it it just
did not appear to be there.
I tried it again this morning with a developed drawing with many layers. All of them were copied into MoI just fine. Of course I lost
things that MoI does not include such as text, line weights, and line styles. That was fully expected, of course.
I apologize for the confusion and am a little chagrined.
cheers,
eric
