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.
Imports invisible geometry.
