first of all i just have to say i love this program. with school and all ive never had enough time to learn 3d max or rhino but this is just so easy to use! a problem im having tho is that i dont know how to create a nurb surface. ive used max before a few times and when you create a nub surface (like a simple plane) you select how many control points you want in the x and y direction. are these control points available in moi? ive tried creating a rectangle and adding points but tat doesnt work. i also used the merge command to try and break the face up into points but that didnt work either. all im looking for is a way to draw a plane and activate control points which let me morph and edit it easily.
