Colors and Layers in Imported Rhinoceros Files
When you import a file from Rhinoceros, it is automatically processed in Creo. This processing includes accommodations for Rhinoceros color and layer information.
Geometry and facets created in Rhinoceros include color information for the following display modes:
Only one mode is active at a time. When the Rhinoceros file is saved, the active display mode is noted. The color assignments associated with the active Rhinoceros mode are read by Creo when the part is imported. For example, if chrome is the color assigned to the Rhinoceros geometry in Render mode, and the file is saved with Render mode active, the geometry appears in chrome (equivalent RGB values) in Creo.
Assembly files cannot be created in Rhinoceros, but *.3dm files can contain geometry on different layers to denote separate parts of an assembly structure. You can import this kind of file to Creo as a flat assembly structure—an assembly in which parts are listed without the hierarchical organization used in files created in Creo.
During the import, a separate Creo part file is created for each layer containing any surfaces, open quilts, closed quilts, or facet data. If a Rhinoceros layer contains exact geometry and facet geometry, the result in Creo is a single part file. That part file contains one Import Feature containing the exact geometry and one Facet Feature for each body of facet geometry. If a Rhinoceros layer contains only datum curves, the datum curves are imported into the assembly file as a datum feature, not into a separate part file. If a layer is hidden in Rhinoceros, the information on it is not included in the import.
