Conflicting Mates
At times a mate can not be satisfied because the components are already
constrained in such a way that they can not move into the mate. The components
can be fixed
or mated to other components.
Example
The bottom faces of these two blocks are mated to the same plane:

If you add a coincident mate between the side of one block and the side
of the other, the blocks can move into the mate:

If you add a coincident mate between the bottom of one block and the
top of the other, you get an error. The first block cannot be simultaneously
mated to the plane and to the top of the second block, because the bottom
of the second block is also mated to the plane.
How MateXpert helps
In this example, when you click Diagnose
in MateXpert,
the program lists three conflicting mates. These mates are the two Coincident
mates to the plane and the bottom face to top face Coincident mate.
When you click on the problem mate, MateXpert
tells you that the mated faces are not coincident, and tells you how far
apart they are.
How you can fix the problem
Delete, suppress, or edit one of the conflicting mates.
You can also use mate
callouts and View
Mate Errors to help identify and resolve mating problems.
