Trim between separate Sketches

[Anonymous]

Sorry to submit what is likely a very simple issue but I can't find an answer anywhere. I have multiple sketches with each having a circle of differing diameter. I want to trim where the circles intersect but it seems the trim command only works within a single sketch. Is there a way to have it look at constructs in different sketches? Project attached.     Jack

You are correct that Trim only acts on geometry in the current sketch.  If you use Project, you can project sketch geometry from one sketch into another, and use that as a trimming tool against curves in the active sketch.
