I’m using Kiri in Onshape. I’m cutting several parts at once. See below:

I’m using outline to create these toolpaths. However, when cutting the marked handle area, the piece becomes loose and jambs my router.

I want to completely remove the handle area marked with the arrow without removing the void areas in the other two parts. Is there a way to restrict the rough operation to just this one part?

Hi @Brad_Strahm and welcome! The easiest way to do this is to add a small tab inside that area. That will leave a segment connected that you can manually clean up at the end of the job.

At this time, there is no way to omit specific objects from an operation. I am considering the best way to do this in the UI.
