I am almost new to rhino and I am interested to use Rhino’s free form curves. I had a couple of questions: when drawing a closed free-form curve, I noticed that the method of “wrapping control points” is used, is that a choice in Rhino? Meaning that can other methods such as “wrapping knots” be used to draw a closed free-form curve?
Are the number of knots predefined as a function of number of control points? Or can it be modified (increased)?
Also, what are the usual steps to take after importing a dwg file to make it usable in Rhino?
Thank you very much,
