When you change the geometry of a component so that the mate can no longer be satisfied, the mate becomes dangling.
Example
A concentric mate exists between the shaft and the small diameter on the cap. Later, you add a fillet to the cap, eliminating the small cylindrical face. The concentric mate to that face can no longer be solved.

Edit the mate to include different entities.
-
Use Replace Mate Entities to select a different entity (such as the larger cylindrical face in the example above).
