I am trying to get this sketch to extrude, but it is not selecting the sketch... the extrude works for other figures just not the one I want. Only lines get selected individually. what could be wrong?
You have open profiles, look on circles, fix it. Have a look!
You can also locate the open profiles yourself, in any sketch, by using Check Sketch for Feature (Tools > Sketch Tools> Check Sketch for Feature) or go straight to Repair Sketch tool.
