C4 import options
 
 
 
Group

Determines how files stored in C4 file format are retrieved. When ON, objects are retrieved as a single group for easier manipulation.

Annotation

Enables (ON) or disables (OFF) the processing of supported C4 entities that have been flagged for use as annotation.

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

Scale Factor

Changes the size of models stored in C4 file format as you retrieve the file.

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.
