1)I would know, when you model cars in Rhino, wich tolerances you set, and wich mesh settings do you apply.
2)I didn't find a way (in Rhino) to "planarize" a curve a la Studio Tools.
I'd like to use the "Set points" tool but, instead to be limited to axis choice, I would be
able to define the plane starting from first point of the crv, ending to the last, and so the inner ones should align whit them "planar" .
I look for something like Planar Sections=On when you build blend srfs, but on a single
crv. Think it could be really useful in building our patches.
