CATIA V4 import options (Windows only)
 
 
 
Keep Topology

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

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.

Import Invisible

By default this option is ON.

By default, CATIA invisible (not datum) entities are converted to Alias invisible entities.

When OFF (-v option specified for C5ToAl), CATIA invisible (hidden) entities are ignored and are not converted.

Import Infinite

By default this option is ON.

CATIA entities which are considered as having an infinite geometry (for example, lines, planes) are converted by default.

When OFF (-x option specified for C5ToAl), CATIA infinite entities are ignored and are not converted.

Import Curves

By default this option is ON.

CATIA parametric curves (Type 3), composite curves (Type 24), and NURBs curves (Type 46) are converted to Alias curves.

Import Points

By default this option is ON.

CATIA points (Type 1) are converted to Alias points.

Import Meshes

By default this option is ON.
