Tolerance

Refine the draft accuracy by reducing the tolerance value, for example to 0.1 or 0.01. If you wish to have a coarser draft accuracy, increase the tolerance value, for example to 1 or 10.

Note: A small tolerance value will make the model slower to handle. Due to this, you should perform the faceting after finishing the model.

Angle tolerance

The angle tolerance affects the mesh formed by triangular faces on rounded surfaces. If you decrease the angle tolerance value, the number of triangles increases and the shape of the surface becomes more detailed.

Triangles

The number of triangles to be rendered. The more triangles, the heavier it is to handle the model.

Acis Tolerances

You can select either Use Acis Default Values or Use System Settings Values. By default for older models (created before version 2020) system settings values are used and for new models (created with version 2020 or newer) Acis default values are used. System settings values are less strict than the Acis default values and may cause problems in some imported models.

With the acistoleranceused keyword you can define which Acis tolerances the program will use. The keyword can have the following values:

acistoleranceused	Description
0	Acis default tolerances are always used.
1	System settings tolerances are always used.
2	Systems settings tolerances are used for old models and Acis default tolerances for new models.
