Mate Errors

FeatureManager Design Tree Mate Symbols and Error Messages

Icon and Error Message Explanation What to Do
(None) Mate is OK. No action required.
Mate type is grayed out. For example:

(No error message)

Mate is OK. One of the parts used in the mate is suppressed so the mate is temporarily inactive. The mate will reactivate when you unsuppress the part. No action required.

"This mate is over defining the assembly. Consider deleting some of the over defining mates."

or

"This mate cannot be solved. Consider:
  • Deleting this mate.
  • Moving the assembly closer to the required solution with dragging.
  • Adding more mates to further define the assembly.
  • Changing the mating scheme."
Potential causes:
  • Another mate in the assembly is attempting to violate this mate (the offending mate displays the symbol).
  • The mate and an already-existing distance or angle mate are redundant to each other.
  • The mate is attempting to locate a component that is fixed.
Look for other mates with the symbol. If found, investigate those first because they often cause this error.

See Techniques for Fixing Mate Problems.

Various messages. For example:
   
"One of the entities of this mate is suppressed, invalid, or no longer present." The mate is dangling because one of the entities (face, edge, plane, etc.) is no longer in the model.

Example: Mates to Dangling Geometry

This is generally caused by editing, suppressing, or deleting a part feature, or replacing a part with another part that is missing the mated feature.
Suppressing an entire part does not cause this error.
If a similar entity is available, edit the mate and select the new entity, or use Replace Mated Entities. See Mated Entities PropertyManager.

Otherwise, delete the mate and create a different mate to perform the same function.

"Cylinders are not concentric. Distance between centers is n mm." This mate is trying to move a component in a way it cannot move because the component is either fixed or constrained by other mates. See Techniques for Fixing Mate Problems.
