Trimming a surface with the Surface:Trim tool generates "Closed edge in multi-edge wire" error

Trimming a surface with the Surface:Trim tool generates "Closed edge in multi-edge wire" error message when used as a path. The untrimmed surface works as expected.

Enclosed is an example project for the error. Component "Guides for sfc and path" creates a helical surface via use of the Surface:Trim tool. The path is on the inside (where the cone is).

A sub-component uses this surface to generate the triangular solid helix. A plane on path from the inner surface edge defines the plane for the triangle profile. The subsequent sweep used the same path as well as the surface to generate the solid triangular helix.

Another sub-component attempts to use a ruled surface to trim (Surface:Trim) in the XZ plane (for this example). In this case the Sweep generates the error message. Ditto using a plane as the trimmer.

I don't know if this is a bug or no. For now I'll can go back and generate another solid helix (or use the existing one) and cut that. I think that should work. (It did)

thanks,

Interesting. It took me a little while to recreate the issue, so in case it helps someone else investigate, here's a video getting to the reported error.

Looks like extending the guide surface a bit, backwards from the start of the sweep path, enables the sweep to complete without error. Not sure why this helps but it could be a useful trick to make progress.

Hi Jean,

thanks so much for the video. I'll apply the "solution" when next I visit that project.
