I'm a stained glass artist using Illustrator to create patterns and cutting templates. I'm always looking for ways to simplify and automate things.
My designs are ultimately just a series of paths crossing each other on a simple Illustrator artboard. Here's a zoomed in example of an intersection of two paths where 4 pieces of glass would meet.
I'd like to automatically have the paths be a different stroke width or color a specific distance (say for example, 2mm) leading up to the intersection along each path, to speed up measuring the lengths of joining material that happens at these intersections. I know that I can do this manually by creating a 2mm circle centered at the intersection, using Pathfinder->Outline, and deleting the parts I don't need. This then lets me control and stroke or color the lines leading up to the intersection, as needed.
For small designs, this workflow is fine. For large designs (100s of intersections), this would be pretty tedious, and not worth the effort. Is there any way to automate this a bit using the path offsetting tools or scripts or something?
