Hello everybody

This is what I'm trying to accomplish



I have these 2 border-only circles and I want to cut the part of the blue border which is "inside" the red circle. I tried union, difference, intersection etc. but I couldn't find a way to get this. I also tried to convert from stroke to path before using difference, intersection etc. but I couldn't find a solution.

Background is transparent (inside circles too).

Could you help me?

Hi.

Boolean operations result in closed paths. You will need to edit out unwanted segments of the path.

If those paths have strokes but no fills:
duplicate the red one (Ctrl+D), add the blue below it to the selection (Shift+Click) and press Ctrl+-,
then use the node tool to unconnect nodes between the intersection points of the blue path.

If those strokes were converted to fills:
duplicate the red one (Ctrl+D), add the blue below it to the selection (Shift+Click) and press Ctrl+-,
then select the blue path, break apart (Ctrl+Shift+K) and delete the unnecessary (previously sub)path.

First solution can render better, the latter can produce small "gaps".

Thank you very much!
