Validating Routing connections
You can test the validity of Routing connections and view the test results using Check-Mate.
You can:
- Check parts in the Routing Mechanical and Routing Electrical applications.
- Visually inspect the connection check results.
- Configure a callback to determine the validity of connections.
Note: If you do not use callbacks, NX relies on design rule results to check connection points in a part. To determine the validity of the connections, NX checks if the vectors for the connected ports are opposite and collinear.
- Override invalid connection points and record a justification. The overridden invalid connection points appear as valid in the display. For example, you can change an invalid connection point to a valid connection point using the Force Valid option and record the justification for overriding the connection point status.
- Filter the results of the checks according to the status of connection points.
Connection point statuses
| Status | Meaning |
|---|---|
| Valid | Indicates that the connection point was determined to be valid by the tests that were run. |
| Invalid | Indicates that the connection point was determined to be invalid by the tests that were run. |
| No connection found | Indicates that the connection point contains a single port. |
| Overridden | Indicates that an invalid connection point was changed to valid. |
Tip: You can customize the callback and specify your own conditions and parameters for checking the connections.
