ModelerProperties

Use FACETRES system vairable

Sets the spaUseFacetRes user preference.

Controls whether the FACETRES system variable is used.

0 = do not use Facetres; 1 = use Facetres

Surface tolerance

Sets the spaSurfaceTol user preference.

The surface tolerance specifies the maximum distance between a facet edge and the true surface. The proper value is dependent on the model size.

Normal tolerance

Sets the spaNormalTol user preference.

The normal tolerance specifies the maximum normal deviation allowed between two normals on two adjacent nodes, expressed in degrees.

The proper value is usually independent of the model size.

Mass Properties

Sets the MassPropAccuracy user preference.

Specifies the relative accuracy required for mass properties calculations. Since the specified accuracy is relative, the calculation result depends on the magnitude of the calculated value. A proper value lies between 1.e-2 and 1.e-12.

Maximum number of grid lines

Sets the spaMaxNumGridLines user preference.

Specifies the maximum number of grid subdivisions.

This prevents the facet data of a face from getting too big.

Maximum facet edge length

Sets the spaMaxFacetEdgeLength user preference.

Specifies the maximum length of a side of a cell in object space.

Since a facet cannot be larger than the cell, this determines the maximum size of a facet.

Grid aspect ratio

Sets the spaGridAspectRatio user preference.

Specifies the approximate aspect ration of each cell in the grid.

If the value is close to 1, then the cell is close to a square. This does not guarantee the aspect ration of the facet, which may consist of only part of a cell.

Adjust mode

Sets the spaAdjustMode user preference.

The adjust mode is used for triangle smoothing.

Grid mode

Sets the spaGridMode user preference.

Controls how gridding is used in the mesh process.

Triangulation mode

Sets the spaTriangMode user preference.

Triangulation mode identifies which portion of the mesh is to be triangulated.

Minimum number of  U grid lines

Sets the spaMinUGridLines user preference.

Controls the minimum number of U grid lines.

A least this number of grid lines are generated in U direction.

Minimum  number of  V grid lines

Sets the spaVGridLines user preference.

A least this number of grid lines are generated in V direction.

Hidden line removal resolution

Sets the AcisHlrResolution user preference.

Specifies the accuracy to be used for mass properties calculations. This accuracy is relative: the accuracy of the result depends on the magnitude of the calculated value. Acceptable value range: 0.01 - 0.000000000001 (1.e-2 to 1.e-12).

Specifies the smallest distance taken into consideration during Hidden Line Removal calculation. A negative value means that auto-calibration based on the size of the model will be used. This is highly recommended. When dealing with objects that have very small sizes the value can be set to 0.001 or smaller.

The value of the AcisHlrResolution user preference can also be set in the FLATSHOT dialog box.
