When editing the radius of an arc, I get the message "Invalid Element. Unable to solve rule please correct element construction." What is causing this warning message?
This message can be issued for any number scenarios where the geometry of the element being edited can not be resolved with the new value. The video below shows an example where changing the radius causes the arc to no longer be tangent to the source element when the radius is changed.
