Sweep along spline with adjustable parameters

[rhelms77]

I'm trying to create a pair of glasses with adjustable dimensions. I created a spline and now I want to sweep a profile along it to create the frame. The position and shape of the spline depend on several parameters. When I adjust the pupillary_distance, the sweep fails even though the path seems to be fine. Here is a very simplified example: https://a360.co/2KwIVOi

Values smaller than about 80 mm always fail. Can someone help me understand the problem?

@paul.clauss This looks quite buggy as the sweep should not really be failing that early. Even when the diameter is changed to 2mm it fails too early and then changing the pupillary distance back to lager values that previously worked the sweep still fails.

Also, I've tried to pull the timeline marker back to before the sweep and then delete all features after the timeline market and Fusion 360 crashed reliably.

@rhelms77 You can achieve the same with the pipe tools but then you are stuck with circular, square or triangular  profiles..

@paul.clauss, I'll take this one.  Yes, this seems to be a modeling bug.  I'll send it to the kernel team to look at.

@rhelms77, thanks for sharing the design.

yes, there is something wrong with Sweep in this model.  I filed bug FUS-41491 to track it.  Strangely, the sweep works if you turn off design history (direct modeling).

Thanks for the help everyone. Is there a way for me to know that status of this bug?
