Hello, I'm using Solidworks 2009-2010 and for some strange reason, recently, when I have gone to sketch two ellipses or two circles that have the same centrepoint, it classifies the two separate sketches as one individual sketch. I don't want this, because it won't let me to extrude one and extrude cut the other. So I want to know how to separate these two sketches into their individual parts, as I have not found a way to do it yet. Thank you.
You can use one sketch for more than one feature. After using it the first time it will be absorbed by the feature in the tree, but you can expand the feature, select the sketch, then select the next feature while the sketch is still highlighted.
