Seems to me the nurbs to polygon conversion is used quite commonly in the tutorials. I cannot figure out the different options that are available in the option box. When do I use general vs. standard vs. count vs. control points. What is chord height ratio mean or fractional tolerance or 3D delta or minimal edge tolerance. The tutorials tell me to always use control points but I am not sure why. Any forthcoming explanation would be much appreciated since I can't find the information anywhere.
