Thanks for your reply! What do you mean by CV’s ? The points ? When I use the editPton I can drag and move each individual point along the x,y,z axis but getting it to look like a nice smooth curve is what I am struggling with. I am still a newbie at this software. (I am a lot better at solid wor…

[image] Hussain: CV’s ? The points ? yes. CV = Control Vertex
