Offset tool causing gaps but only for projected curves or when I use trim. Bug?

I don't understand this interaction, in certain circumstances I can get an offset spline to put the first part on the wrong side of a break line.  Like this:

Here is a video:

The audio is really quiet, I'm having mic problems with my new computer and haven't figured it out yet.

Hi! I believe this is either a bug or a limitation in the way a spline curve is offset. You may consider using Extrude command to protrude the curve as a surface body. Then create an Offset surface at the desirable distance. After that, project the edges from the Offset surface to the sketch. This may work more reliably.

Many thanks!

Thanks for writing to us.

We have created ticket FUS-194072 for the issue where break command is not showing correct results.
Our team will analyse it further more and will provide a fix.

Thanks,
