Sketchy, I don't think they were going for a precision modeler! Luckily I don't need one. All I know is that when I want to move a vertex and have it follow the geometry around it, I can do it. If I want to weight an edge gradually along its length, I can do it. And so on. It works for me. In a perfect world I would like modo with nurbs support. It already has some spline patch support so who knows what the future will bring. Sorry if this all sounds like a promo but you know how things get when you find a program you like.
Thomas, sorry to hijack your thread for a moment, I'll go now
