Group

Determines how files stored in VDAIS file format will be retrieved. When ON, objects are retrieved as a single group for easier manipulation.

Annotation

Enables (ON) or disables (OFF) the processing of supported VDAIS entities that have been flagged for use as annotation.

Coalesce Params

Enables (ON) or disables (OFF) multiple knot removal in curve or surface geometry read from VDAIS files containing parametric spline curves or surfaces.

The default is OFF.

Note

If for any reason the trimming fails, the translator will try to trim with the alternative curves.

Default Trim Curves

Selects the trim curves that the processor will use. You can select parameter space curves, model space curves, or use the flag that is present in the.VDAIS file.

Scale Factor

Changes the size of models stored in VDAIS file formats as you retrieve the file.

Level Mapping

Determines how the level (layer) information associated with an VDAIS entity is mapped to Alias Set and Alias Layer information.

Trimmed Surface Optimizations

Shrink Surfaces

When ON, Alias detects trimmed surfaces whose trim boundaries are the same as, or iso-parametric to, the natural boundaries of the untrimmed surface. It then converts these surfaces into Alias surfaces by shrinking the untrimmed surface to the trim boundaries.

When OFF, Alias converts all trimmed surfaces of this type to Alias trimmed surfaces.
