It would be great to have an optional setting to turn on automatic geometry sizing. If I am creating a sketch and have already drawn a 10mm circle and then want to draw another circle of the same size, it would be nice if I could expand the new circle to about the same size and it would give me the option to snap to the same size as the first and automatically create that dimension for me. This should be an option that can be turned on/off in application options.
