VDAFS Import Options

The VDAFS reader uses the vdafs_reader.ini file with the following available options:

@BreakAngle

Value

Description

double

A negative value (default) indicates that the curves are being split at C1 discontinuities.

A positive value indicates that curves are being split at G1 discontinuities with an angle greater than the given value (expressed in radians).

@CleanupTol

Value

Description

double

A negative value (default) means to use the auto cleanup tolerance. A value greater than the calculated auto cleanup tolerance means to use that specific tolerance.

Refer to the CAD Cleanup Tolerance section.

@DoNotMergeEdges

Value	Description
on	Preserve the original geometry edges, instead of merging them together during the import cleanup phase.
off	Merge edges together during the import cleanup phase (default).

@ImportForVisualizationOnly

Value

Description

Import the model for visualization purposes only.

This skips many of the import steps (cleanup, stitching, solid creation, and so on) to provide a faster import. The resulting model may not be suitable for other uses.

off

Import the model in the normal fashion (default).

@ImportFreeCurves

Value	Description
on	Import free curves (wireframe entities) into the model (default).
off	Do not import free curves.

@ImportFreePoints

Value	Description
on	Import free points into the model (default).
off	Do not import free points.

@MetadataPrefix

Value

Description

string

The string is prefixed to all metadata names. No prefix is used by default.

See CAD Metadata Naming for more details.

@ParameterTolerance

Value	Description
Any positive real number.	The reader considers this tolerance as the parametric tolerance used to process the CAD data. The default value is 1.00E-06.

@Planes

Value	Description
on	Treat each surface as found in the CAD file (planes/NURBS).
off	Convert planes into NURBS surfaces.
preferred	Convert NURBS surfaces to planes if they are within the object space tolerance of being planar (default).

@ScaleFactor

Value

Description

double

Defines the model scaling factor during import.

Default is 1.0.

@StraightPolynomials

Value	Description
on	Treat each polynomial segment as a straight line segment. This is necessary for reading some VDAFS files, COMPUTERVISION CADDS 4X in particular.
off	Treat each polynomial as found in the CAD file (default).

@TagsAsMetadata

Value

Description

Read tags of supported entities as metadata (default).

TAG

off

Do not read tags.

@Tolerance

Value	Description
Any positive real number.	The reader considers this tolerance as the object space tolerance used to process the CAD data. The default value is 0.01.
