I'm trying to model the vanes on a 3D unshrouded centrfugal impeller.
The disk & hub is a simple revolve.
Ideally, the vanes would be a thickened lofted surface whose profiles are simple straight lines normal to a 3D spline guide curve on the revolved face of the disk. Unfortunately, SW doesn't seem to be able to do this.
I can draw the 3D spline on the face, but cannot draw simple straight lines normal to the revolved surface, even when using multiple reference planes along the curve. I cannot seem to sketch points at the intersection point between a reference plane and a line normal to it.
Any and all suggestions are welcome.
Regards,
Tom
