IGES File Format
The International Graphics Exchange Specification (IGES) is a standard format for model geometry. PRIMER will read fixed ASCII file format 5.3 IGES files.
The following IGES entity types are read by PRIMER.
| Entity type | Entity description | Notes |

| 104 | Conic arc | Forms 2 (hyperbola) and 3 (parabola) not supported. |
| 106 | Copius data/Linear path/Simple closed planar curve | Forms 1, 2, 11, 12 and 63 supported |
| 108 | Plane | |
| 110 | Line | Forms 1 (semi bounded) and 2 (unbounded) not supported |
