how to convert a surface into a mesh and back?

(and maybe you kill me for this but, where are the exact differences between the mesh and the surface? only a few options are different?)

I'm assuming that when you say "mesh" and "surface", you are referring to "polymesh" and "surface". The difference is that a polymesh is simply and polygonal object and a surface is a NURBS object. NURBS to polymesh is quite simple. Select your NURBS object and click on modify>polymesh>surface to mesh (I think thats it). Going from polymesh to NURBS has in the past been difficult or impossible but in XSI there is a hidden feature that will do this. Select your polymesh object and open up the scipt editor. Type: ApplyOp "PolyMeshPNet" and hit "run" at the top. Its crude but usually works.

hey Kris

that's awesome. I had no idea there was anything to do that other than manual construction.

Love your work,

Doesn't work for me. What version are you using? 2.xx?

I'm using 2.02. Create any polymesh object, select it, open up the script editor, type:

ApplyOp "polymeshpnet"

Still doesn't work. But its a great script for a Critical Meltdown! AND with the option to save before failure! Wink.

I'm on 1.5. I'll try v2.0 when we get it.
