Hi delic, I'm glad you are getting good results now!

re: network U and V selection - you do need to have curves that make up logical U and V directions but you don't actually need to select them in that order, the Network command automatically analyzes the layout of all the curves and sorts them into U and V sets for you. So you should be able to do a group select and get the same result. Selecting by individual clicks in order will not actually have any effect, this is an area that is a bit different between Rhino and MoI.
