Use the Repair environment to analyze the quality of imported data and repair surfaces or solids for use in part modeling. After data is repaired, the repaired body participates in the model history.
Some of the errors occur during translation, or are the result of loose modeling techniques. These errors include:
- Self intersecting surfaces or curves
- Intersecting faces
- Modeling uncertainty (miscellaneous topology and geometry errors)
- Irregular surfaces
- Face normal direction is pointing the wrong way
- Gaps between surfaces
- Holes in surfaces
- Overlapping faces
You can detect and repair these errors using specialized tools found in the Repair environment.
Find Errors examines the selected bodies for errors in topology, geometry, and modeling.
In the browser, the repair node (
) marks the data with one of the following icons:
-
Healthy geometry. 
Geometry requires further checking. (Geometry may contain topology and geometry errors; this geometry can fail in downstream modeling operations.) 
Geometry contains errors (such as overlapping or self-intersecting faces) and requires repair. Errors in the repair node are in an error folder (
) Heal Errors fixes errors in the selected bodies using the Allowable Change tolerance value.
Note: To preview the number of errors fixed by the specified tolerance value, before you click OK, use Analyze Selected Bodies.Use the surface tools to repair data not fixed by the Heal Errors command.
