So Gary, I'm with you in that the answer here is to just delete and redraw the slot. In the context of doing one sheet that absolutely makes sense. However, I'm bringing in these cabinet side panels from SketchUp (they're actually exported to AutoCAD format, and then brought into Aspire)
The problem is that this problem scales. If I have 15 sheets to cut with 75 of these little pockets, the time it would take to redraw them is a lot, and the chance of missing one is much higher. Also, I want to "idiot proof" this process as much as possible as I may not be the only one operating the machine using this workflow.
If the slots were just a hair under .25 in some cases that can be cured very easily with adding a tiny offset to the toolpath. That solution scales very well from one slot to 100 slots.
The problem I have here is that the solution that is supposed to work (offsets) doesn't, at all. It's like there's something borked with the way those slots are drawn. Despite checking, rechecking, re-importing, redrawing I get the same bug over and over. If this was just an inconvenient work flow thing, I'd figure a way around it, but here I do believe I've found a bug.
