Hi I am trying to do some hairpin motor windings that involves sweeping a rectangle around rounded hollow tube. as it needs to be procedurally changed it is not practical to use a roll ramp before the sweep.
My problem is I have normals on the curve that I have tried to convert into my up vector but I still have strange twisting no matter what I try?
I have a preview of what I am trying to achieve
I found using the roll ramp very hard to get right and be totally accurate each time the windings changed
Getyamamout Hay Tamte I thought that is what I was doing by promoting the normal to be "up" then adding a polyframe to get the curve normals?
middle click in the Attribute Promote, you will see the warning that no promotion is done Attrib Promote is to promote attribute among different classes (Point, Vertex, ...) or to pieces of the same class
also you can always attach a visualizer to your attribute to see how it looks, in your case visualize N and up to make sure they are what you expect before Sweep
