How to quickly delete section or part of path(s)
I have a file destined for a laser cutter. It was imported from dxf format so it consists entirely of individual paths that are end to end.
If I run the file in the laser cutter as it is, as the laser cuts a lot of small pieces will fall out and get lost. I want to create small tabs to hold these tiny pieces in place.
I've been trying to find a (hopefully) quick and easy way to delete sections of some of the paths (so the laser doesn't cut there and the piece stays in place) without deleting whole paths. I'd also like the sections I delete to all be the same length so I tried creating a circle and using Pathfinder > Minus Front, but that gives me the error "The filter produced no results. Please select two intersecting paths."
I tried to show what I want in the image below. Is there a (hopefully) fast and easy way to do this? Thank you!
