Sweep along parametric curve not rotating about axis

Greg_Daly

Hi all,
I'm trying to sweep a profile along a parametric curve. When I sweep it along a helix, I get what I want, but when I sweep it along a parametric curve, it doesn't rotate the profile about the x axis/origin.


Left view: Helix on outside, parametric curve on inside.


Front view: Helix straight line, parametric curve sine shaped.



Resultant sweep: the parametric curve-based sweep is acting as if I selected "keep profile orientation" but I did not.

Any ideas on how to force the sweep to rotate about the origin and not keep the profile orientation?

Thank you!

Hi @Greg_Daly, try using a custom feature.
Sweep normal by @mahir should do the trick. 

There is a little + icon at the top of the documents page, click that to add the feature to your toolbar.

Hey @MichaelPascoe, I had tried Sweep normal before, and couldn't get it to work. Based on your comment, I gave it another shot and got it! Here's what I did, for posterity (and others in the future that have the same issue):

step 1: extrude a cylinder with the same radius as my figure:

Step 2: use the surface of the cylinder as the reference for sweepnormal:
