From the Check and Repair section of the action bar,
click Geometry Checkers
 , and select the
geometry to check.
- Select a Visualization mode.
 Show all.The selected geometry is made translucent. All faces with an issue are colored; non-manifold edges and edges comprising a sharp angle are highlighted. -
 Show all issues only.Geometry with no issues is hidden. Coloring and highlighting are applied the same as for Show all. -
 Show current issue only.Geometry with no issues is hidden. Coloring and highlighting are applied for only the selected issue type. A clipping box is created, and the view is adjusted to focus on the selected error. You can use the Define Box  tool to adjust the clipping box. Note:
The clipping box remains open, even if you close the Geometry Checkers dialog box, to assist you in correcting the geometry.
- Select the Issue type.
| Option | Description |
|---|
| Non-Manifold edges | Edges shared by three or more faces. |
|---|
| Sharp Angles | Angles that may force poor mesh element shape. |
|---|
| Slivers and Inclusions | Slivers are small portions of the model that are not connected to the main body. Inclusions are small voids within areas that are otherwise solid. |
|---|
- Adjust the threshold detection level for sharp angles or slivers and inclusions, if necessary.
The value for slivers and inclusions is the volume ratio of a disconnected feature or void compared to the volume of the entire model. Features smaller than the specified values are highlighted as issues. -
Select Autofocus to focus—or zoom in on—the current issue selection.
- If there is no issue currently highlighted for the selected Visualization mode, the first issue that is detected receives focus and becomes the current issue type.
- If an issue is currently highlighted, this issue receives focus.
Use the arrow buttons to highlight and switch focus between the issues in the current display set. You can also display a list of the issues.
