Checking Model Geometry

By default, each time you add or modify a feature, the feature is checked against any adjacent faces and edges. Additional tools for checking models are the Verification on rebuild option and the Check Entity tool.

You can use these tools for the following purposes:
  • To examine imported geometry (when you import the body as a whole, from another system, such as an IGES or STEP file)
  • To make sure that the model exports properly to other formats
  • To determine the cause when the model looks wrong
To increase the level of error checking, turn on the Verification on rebuild option. When this option is turned on, the software checks every new or changed feature against all existing faces and edges, not just adjacent faces and edges. Features that cause invalid geometry fail when this option is turned on.
This option has a negative effect on performance. Rebuilding the model is considerably slower and more CPU-intensive. This option applies to all documents, not just the active document. Use this option only when needed, then be sure to turn it off when you are done.

To verify the model with a higher level of error checking:

  1. Click Options (Standard toolbar) or Tools > Options.
  2. On the System Options tab, select Performance.
  3. Select Verification on rebuild, then click OK
  4. Press Ctrl + Q to regenerate the entire model.
    When you press Ctrl + Q, it causes a complete rebuild of all the features in the model. The Edit > Rebuild operation (Ctrl + B) only rebuilds new or changed features and their children.
  5. Examine and correct any features that fail, beginning with the first failed feature in the FeatureManager design tree. Often fixing one failed feature allows subsequent failed features to rebuild successfully.
  6. When you are satisfied that all the errors are corrected, repeat steps 1 and 2, clear Verification on rebuild, then click OK.
