I have inserted a Cbore for a 1/4 inch screw and the sketchdefining the through hole has an error in it which I can notchange. Is there a way to modify the hole after it is inserted? Ihave tried removing and reinserting with nor luck. I can insertother sizes with no problem

Here is the message I get.

Warning Sketch4 The sketch has not been updated because solving itwould result in invalid geometry (such as a zero-length line).Consider : o Deleting the invalid geometry. o Changing relations ordimensions to eliminate the invalid geometry.

Thanks
