What I mean is: it's usually best to think ahead in these situations.. copy the lines when they're more selectable then paste in place once the surface is made..

Thanks Jeff, that is what I want!

The real name of this plugin is Curve Scale by sugar

Ok, no problem. I did find some tutorials that answer some of my questions on the Paracloud website.

I have seen something similar at tgi3d. Not sure if these figures specifically can be done.
