Here is a picture I tried to flat the blasted pipe. Like I said before the Curved point on the wall is magnetic nurbs and it only attracts any nearest polygons. That is why I think it need X, Y, and Z selection for better curve control (nurbs) including separated paths. It is kinda hard to make separated spline for each object because I would have to use little scene preview to make the ribbon to fit in. IT is very simple with curved pipe and ribbon but not with my other complex models. My other complex models are not just with pipe and ribbon, they are made with some complex shapes. I had to overwork to make it the exact model I had in mind. I can not post my complex models here to preserve my models from copying. I would like to see some improvement in Spline with XYZ selections with ability to separate paths for better curved point control for any polygons within path. It is for advanced and complex modelers. Waldoo.
