Hans I am sending the hand drawing,,, why am I sending it?
just to give you the idea of what I'd like to realize with SH3D.

Plug-ins
I tried to install the plug in accordingly to the procedure...
And I tried both procedures you indicated me...

And it is not working on the desktop (win8) and the notebolok (win7)
May be I just have to disintall it and start from scratch...

Anyway thanks for answering...
very nice of you

regards
