Parameters

QualityNum

Number between 0 and 106 that indicates the quality of tessellation to use for this part (see Remarks)

This method changes the shaded-display quality setting on your system, not just the current document. The numeric deviation value changes based on the current part. This deviation is calculated as follows:

QualityIndex = TessMin + QualityNum*((TessMax-TessMin)/100)

Deviation = 0.025 * (BodyDiameter) / QualityIndex

where BodyDiameter is the diagonal distance across the bounds of the part box. See IPartDoc::GetPartBox or IPartDoc::IGetPartDoc for details.

The resulting deviation value is in meters.

Use IModelDoc2::GraphicsRedraw2 after using this method to update part.

NOTE: Setting the index of the tessellation to a higher value results in:

• finer tessellation,
• increased file size,
• slower graphics performance, and
• increased memory usage.
