Sweep changes when closing edit.

[jan_murberger]

EDIT: Sort of solved. The sweep would not sweep top to bottom, but from below it worked. Original post: When editing this sweep it looks ok. If I close edit, it will change. What is going on?

Welcome to the forum.  I have moved your post to this forum since this might better be answered as a design question. Good luck.

I am going to tag @Phil.E the one formidable force here on the forum in the fight against evil bugs!

It's hard to say this is a bug entirely. Sweep is giving errors with this geometry, most operations are blocked. This is partially due to extracting the coil edge from a primitive. It's not your fault that sweep is in deep water here.

I tried a few workarounds. Surface sweep, and an eventual Boundary Fill operation, seem like a promising way forward. I don't have time to complete it, nor is it obvious what the end state is going to be. But this gets you something more.

I will notify the team that works on sweep.

@jan_murberger ,

can you share what the finished geometry is supposed to look like?

Is this it?https://digitaltmuseum.se/021018091767/statens-jarnvagar-sj-buffert-1898-ars-modell

is it some sort of spring?

@jan_murberger 

Is this what you're trying to accomplish?  If it is I'll post a little video of how I got there.

I edited my original post with the solution: to begin from the bottom. Then it worked. I can even overlap the sweep and it should not be possible, To me it was a bug, because when examining the problem the original sweep went into symmetric mode, sending my start point to the middle of the sweep, also causing multiple attempts where I got the alarm that it is overlapping itself.

Yes, it is this spring. I had this image and original drawings as reference. Though, everything has to be modified and compromises has to be made since it is a very small scale. Please post a video, because it is always nice to see how other users approach things.

Thank you for the input. I am making my first real designs, so a lot is new to me.

Hi @jan_murberger as promised, here is a video and my sample file.
