# Re-Tessellate

Set tessellation parameters in the importer settings or use the re-tessellate context menu command to re-tessellate the model within the current 3D work space.

To re-tessellate a part or assembly:

**Select the parts**or assembly either in the graphic area or in the assembly tree.- Right mouse button click to bring up the
**context menu**. - Select
**Re-tessellate...**.

## Tessellation Level

The predefined quality of the tessellation that will be generated for B-Rep data using the standard tessellation algorithm.

## Tessellation Preserves UV Points

Whether to keep parametric points as texture coordinate when generating the tessellation for B-Rep data.

## Tessellation Maximum Edge Length

The maximum length of the triangle edges in the tessellation generate for B-Rep data. The value must be non-negative, and if set to 0.00, the length will not be used. when generating the tessellation.

A value too small can generate a large tessellation resulting in a lengthy rendering time.

## Custom Tessellation Types

Utilize additional tessellation parameters (accurate tessellation, angle tolerance, chord limit type, chord height ration, and chor height limit) by setting the **Tessellation Type** to **Custom**.

## Accurate Tessellation

Whether to use the accurate tessellation algorithm. If the accurate tessellation algorithm is not used, the standard tessellation algorithm will be used.

## Tessellation Angle Tolerance

The maximum angle in degrees between two consecutive wire elements i the generated tessellation, in the range (10, 40).

## Tessellation Chord Limit Type

Select **Height** to use the Tessellation Chord Height Limit setting or **Ratio** to use the Tessellation Chord Height Ratio setting.

## Tessellation Chord Height Ratio

The ratio of the tessellation chord height to the bounding box height in the range (50, 10000).

## Tessellation Chord Height Limit

The maximum distance between the surface definition and the tessellation approximation.

A value too small can generate a large tessellation resulting in a lengthy rendering time.
