Abaqus/CAE can import part and assembly geometries from a variety of external sources and CAD systems. The associative interfaces for Abaqus/CAE provide straightforward and powerful techniques for importing geometry. More traditional techniques are also available for importing and exporting geometry using standard CAD file formats. Understanding the capabilities of each format, as well as the limitations of representing the geometry of a part in a file, will help you select the import or export technique that is appropriate for your application. The following topics are covered:
