How to edit a three-point curve that is part of a part

I have a 3D part whose sides are an arc that is part of a circle. They were drawn by setting the two end points and then completing the shape, via the 3-point arc tool. Now I need to change the curvature of the arc but keep the endpoints (increase the diameter of the underlying circle). How do I do that? I tried the Edit Curve command but that doesn't work. I cannot just change the value of the diameter dimension because it is a derived dimension, not a defining dimension. I thought I could just pick the arc center point and move it up or down to change the curvature but I can't find a way to do that, maybe it cannot be done that way. Any ideas?

sounds like you need to investigate the constraints that are on your arc that might be limiting the behavior you’re looking for. Maybe a screenshot or document link might allow someone to help narrow down the issue..

It is the rightmost 19mm dimension that controls the arc curvature. The reason it didn't work initially is that elsewhere I had simensioned the arc with the radius of a circle which made that 19mm a dependent dimesion. When I deleted those other dimensions (which were only added for documentation purposes) it all fell into place.
