solo, I looked it up in the ruby and the initial ruby was also by Didier. So I guess I can put it here on the forum since it was a free ruby. If I couldn't please let one of the mod's remove it.

Solo,
I have a separated ruby that extrudes by vector but I do not remember where I got it. BUT the function is also available in the projection ruby by Didier Bur witch you can find on this forum.
greetings, erikB

Thanks fredo for this wonderfull new tool. Works like a charme and with the use of the icons it seems like if they have always been part of the original program. GREAT scripting !!!

Whaat,
You did it !!!

Whaat,
Looks like an amazing ruby your writting !!
The connection, suggested by Tomasz, between handeling a low poly model en a 'high poly' output model whereby you can change the low poly and the high poly follows seems like a winner (if it is possible), specially since sketchup doesn't handel high poly very well.
Looking forward tot its progress.

fredo,
