We have an addin that we use daily that will copy a solid body, along with named sketches, and insert that into a blank part, and then Iges that file out.   The goal being to eliminate any unnecessary construction sketches from the file so that the files that our CNC department is getting isn't overly cluttered, and contains only the pertinent information.

What I am wondering is, Could it be possible to instead, find any sketches that are being used in features, and include them in the iges file, so that those sketches don't need to be renamed?

This way, the needed items are being exported, even when someone might have neglected to rename a certain sketch.

Or if anyone has any other solution to offer, I would be happy to listen.
