VDAIS import options

Group

Imports objects as a single group for easier manipulation.

Annotation

Processes supported VDAIS entities that have been flagged for use as annotation.

Coalesce Params

Removes multiple knots in curve or surface geometry read from VDAIS files containing parametric spline curves or surfaces.

Note:

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

Default Trim Curves

Specifies the trim curves that the processor will use. You can select parameter space curves, world 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 import the file.

Level Mapping

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

Trimmed Surface Optimizations

Shrink Surfaces

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 this option is not selected, Alias converts all trimmed surfaces of this type to Alias trimmed surfaces.
