I was wondering if it was possible to do a finishing pass for only some cuts?
For example, on this part if I wanted to do a rough cut for the entire shape but then do one more pass just a long the top edge - would that be possible somehow?
It sounds like you want the trace operation
depending on geometry, you have trace, pocket, and outline options. trace selects edges, pocket selects areas, and outline is a global op with lots of parameters.
