Sweep along guide is twisting
Sweep along guide is twisting
(OP)
Hello,
Anyone know how to keep a sweep along guide from twisting? I have extracted curves (from an imported model) as a guide string with some bridge curves replacing the small non-tangent curves. When I sweep a simple cross section, it twists as it goes along the guide string.
In the attached model, I really want the the sweep to remain parallel with the Z axis. The curves represent a groove for a press in place gasket in which a seal will reside.
Any thoughts?

Thanks!

Anyway, take a look (note that I left your old 'Sweep' feature in the model just that it's suppressed, which you can unsuppress to see how it compares to the new 'Swept' feature).

Thank you for your response, I completely agree and it seems you and I did the same operation in this case. I wish we were able to obtain better parasolid geometry to extract the curves from, however that is proving to be impossible from our customer (that also uses NX so native would have been perfect). I'll work with this method and add the complex geometry cross section and the multiple loops to see how it turns out. Thanks everyone!
