I'm trying to use the Split Entities command to divide an existing arc into two arc segments so that I can give them different radius values. I have deleted the CoRadial constraint, but I still can't give them different radii. I think the problem stems from the fact that they share the same center. What's the point of being able to use Split Entities on a circle or arc if I can't actually make them separate sketch entities? They're basically just the same arc with a point in the middle.

Any ideas of how to get these arcs to not share their center point?
