In the Menu Bar, click Edit > Preferences, then on the left side of the dialog box, select Import > Catia V5.
Import Options
Sets the type of surface data imported into the scene. Select from Import none, Import visible, and Import all.
Imports the type of mesh data imported into the scene. Select from Import none, Import visible, and Import all.
Imports the type of curve and polygon line data imported into the scene. Select from Import none, Import visible, and Import all.
Tessellation
Sets the maximum triangle aberration for tessellation from the b-splines. Select from Coarse, Low, Medium, High, and Custom.
Sets the maximum deviation between the NURBS surface and the tessellated surface.
Displays the normal tolerance of adjacent triangles in degrees.
Defines the maximum edge length of the generated polygons.
Enables stitching of adjacent edges.
Sets the tolerance where two adjacent edges are considered to be touching and where they should be stitched together.
Advanced Options
Keeps NURBS data after tessellation, rather than deleting it.
Ensures all surface normals point in the same direction.
Merges the geometries to create one single (stitched) mesh, since a single shell can have many NURBS surfaces.
Items that are originally organized in layers (for example, in Autodesk Alias) are organized into groups. Otherwise, the objects are all placed under the same parent node.
Remove empty (unnecessary) groups.
Shared node instances, used to save system memory, are removed so that nodes exist independently.
Stores the transformation data within objects themselves rather than in higher-level group nodes. In other words, if you have a hierarchy of transformation parent nodes of a geometry node, all of them are baked into one single matrix within the geometry; the original information is lost. You would want to avoid this, for example, for animating wheels on a moving car.
File Specific
Doesn't create additional MaterialGroup nodes for part files, assemblies, or instances, and simple discards the materials, when disabled. For some Inventor workflows, you may want this enabled to create these MaterialGroup nodes.
Imports data associated with your meshes, rather than excluding it.
Imports invisible (hidden) instance data, rather than excluding it.
Toggles the import of all part files and sub-assemblies referenced by the assembly file on or off.
Toggles the import of the Axis Systems from CATIA into VRED. Since CATIA files can have multiple coordinate systems, VRED see these, import them, and create transformation groups with a coordinate cross for a better representation in the viewport.
Choose one of the following methods as the default used for importing Catia V5 files. There should be no differences in tessellation quality, structure, material import, or naming conventions between these methods.
