Hi Dave, so it would probably help if you could make that line script example that leaves a ghost object, so I could run it over here and check it out.

For Trim, I guess it looks like the call to generate fragments will cause UI objects to be created, for things like the endpoints of curve fragments.

The automatic setting of the disable UI geometry flag happens inside of the call to calculate(), so that's why they are not being suppressed automatically, because the fragment generation thing happens before that.

Try calling factory.disableUIGeometry(); before the generate fragments call, that should manually set the flag that disables UI geometry so I think that would then prevent those extra things from being created.
