When this option is checked, curves and surfaces are converted to NURBS geometry.
Converts polygonal geometry to meshes.
Creates a log file containing a list of path names of imported files, a list of warning and/or error messages, and the options string.
Imports points.
Imports curves.
Imports solid and sheet bodies as shells/surfaces, meshes for bodies, or meshes for faces.
Keeps the topology for sheet and solid bodies.
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.
