Hi Len,

If you have a coordinate frame and you want to translate a point from world coordinates into that local frame's coordinates you can do this:

var local_x = frame.distancex( global_pt );
var local_y = frame.distancey( global_pt );
var local_z = frame.distancez( global_pt );


> Also, is there an easy way to select the curve that makes up the surface?

I'm sorry I'm not understanding this part. What is the curve that makes up the surface? A curve used to generate the surface with a particular command? The edges of the surface?
