Surface Tolerance

The surface tolerance is the distance between the facet and the part of the surface it is representing.
This parameter specifies how accurately the facets represent the surface. Set this parameter when facets obtained with the normal tolerance setting do not represent the surface well.

Example:

Max Grid Lines

Specifies the maximum number of grid subdivisions.
The maximum number of grid lines can prevent other constraints from being satisfied, so it is recommended to set it to a high value. If for example you set the Max Grid Lines to 10, this will prevent the normal tolerance from generating enough facets to accurately represent a surface.

Example:

Normal Tolerance

Specifies the angle between the surface normals at the two adjacent nodes of a facet.
Setting this normal deviation refinement specifies how accurately the facets represent the surface and the quality of rendering desired. It is independent of the model size.
