Radius in sketch not constrained, shows over constrained when dimension added

[Anonymous]

Having an issue where when I try to add a dimension to an unconstrained radius it tells me that sketch is over-constrained. I can manually drag the radius smaller and larger, but can't actually define what the radius is. I have provided a screen cast and a few images of the issue. Any help would be appreciated.

For some reason the screen cast didn't show up, so here it is again.

Hi turbocharged110,

Thanks for reporting this issue. I think we have a bug here in the sketch solver system. Could you help share your model here or send it to weining.cao@autodesk.com for us to go on take a look at it?

This kind of false over-constraint problems would happen more frequently if there are sketch offsets included in a sketch. So if you need a quick workaround, you can try delete the sketch offset first (Usually if you only offset lines, delete the offset will automatically add some parallel constraints back), and then you can add back the normal dimension to define the offset distance.  Then you can see if the problem goes away. 

Thanks,
Frank

Thanks Frank. I will email you the file tonight.

As for the work around, thanks for the suggestion, I'll give it a try. For now I just added a reference dimension and dragged the radius until the reference dimension read the correct value.
