I am having trouble with one of my 3D sweeps. Generally, if Pro E tells me that my trajectory is invalid, I use a Swept Blend instead. In this case, my cross-section contains multiple loops and it will not allow me to use this method either. I don't think I can use variable sectional sweeps since I only have one trajectory to work off of. The only other option I know of is to use the Swept Blend feature 5 times since I have 5 loops in my sketch. Does anyone know of a better way?
