Why would a spline made using Objects>Spline Object not sweep properly while a similar spline made using Objects>Create Spline works fine? I spent hours (what noobs do) troubleshooting this. Argh!

Take a spin, the file is attached. Symmetry1=spline via Spline Object. Symmetry2=spline via Create Spline.

The axis if ObjectSplines are often not perfect for sweepNurbing.
If you turn the Axis-Heading (not the Object) 90degrees using the AxisTool (Not the ModellingTool) of your "SplineObjectSpline" it will look the same as the other setup.

A practical example is if you want to SweepNURB a Helix, you first have to change the axis (in AM) to "ZX". Then rotate the Helix to the position/rotation you want.
The default "XY" setting is not "Sweepable", you'll get all sorts of twisting.

Short, sweet and right. I'll add that one to my notes.

tcastudios, I've learned a lot from your posts. Thanks and, for all of us, please keep up the good help.

Cheers
