If this option is checked, solids are converted to Alias shells. Otherwise, they are converted to a collection of trimmed 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.

When ON, entities of type Facet are converted (to meshes).

When ON, entities of type Nurbs are converted

When ON, entities of type Curve are converted

When ON, entities of type Point are converted

If checked, a report containing a list of path names of imported file(s), and a list of warning and/or error messages will be produced.
