Uffff..is very late now

Thx for this link. I didn´t know that it was posible to get transparecy under Windows and with GNU license (but looking at the screenshot, the console window seems like a console from linux) :?

Well, I use a "dirty trick" that I discovered the other day. I suppose that you know that you can download rhino in a evaluation version, with a limit of saves. Then, you can use the feature of Rhino to use a background image, and then.....-the trick-....--> select the curves --> ctrl+c --> MoI --> ctrl+v.....until Michael gives MoI those feature ;-)

Bye!
