When you import an IGES-format file, ABAQUS/CAE scans the contents of the file before displaying the Create Part from IGES File dialog box. You can then use buttons on the IGES Options tabbed page to view the following:
IGES Header
The IGES header information includes details about the application that wrote the IGES file. It also includes information about the author of the file and the date when the file was written, along with the scale, resolution, and units.
Entity List
An entity can be a geometric entity, such as a point, an arc, or a line. Alternatively, an entity can be separate from the geometry, such as a comment. IGES allocates a number to each entity; for example, a circular arc is entity number 100. The IGES entity list displays a list of each type of entity found in the file. The list includes the IGES entity number, a description of the entity, and the number found in the file.
For a complete list of the IGES entities that can be imported into ABAQUS/CAE, see “IGES entities recognized by ABAQUS/CAE when importing a part or a sketch,” Section 10.7.8.
