Question for a CMS iCAD user

[BKT]

Could somebody who has CMS Intellicad (I have version 6.1) try this
for me? I can't seem to get the solid edit shell command to work
properly. If I try to remove a face, the operations fails. It will
do a shell if no faces are removed, but it shells out, not in, as ACAD
does. (Actually, if I enter a negative number for the shell offset
distance, it does shell in.)

Command: _solidedit
Enter a solids editing option: Face/Edge/Body/Undo/<eXit>: _body
Enter a body editing option Imprint/seParate/Shell/cLean/Check/Undo/
<eXit>: _shell
Select 3d solid:
Remove faces: Add/Undo/ALL:
IntelliCAD is unable to complete this operation.
Command: '_PMTHIST

I'd appreciate it if someone could try this. I've tried it in the
newest trial version from CMS and it still fails, but the face removal
seems to work with the ProgeCAD trial version, though it still shells
out.

Thanks!
