How do I make sketch geometry in one block 'equal' to sketch geometry in a different block? I am trying to model a hinged shaft collar that clamps over a 1/2" diameter shaft. The two hinged arms are sketch blocks within an assembly layout. If I change the shaft diameter to, say, 5/8" instead of 1/2", do I have to change the two blocks separately? The two arms are NOT multiple instances of the same block.
