About Importing and Exporting IGES Files
Initial Graphics Exchange Specification (IGES ) is a neutral file format designed
to transfer 2D and 3D drawing data between dissimilar CAD systems. The IGES standard
defines two file formats: fixed-length ASCII, which stores information in 80-character
records, and compressed ASCII. The IGESIMPORT and IGESEXPORT commands support only
the fixed-length format.
Understanding the Limitations
Under ideal conditions, translation preserves the appearance and functionality of
entities. However, this process has limitations, and some data will not be preserved
in a round trip to IGES and back.
For example, when exporting to IGES, a 2D polyline is translated as IGES entity 106:12.
When importing from IGES, entity 106:12 translates to a spline. Hence, if you use
IGESIMPORT to read a file created by IGESEXPORT, the resulting drawing may not be
identical to the original drawing.
Similar data loss may occur when transferring data between AutoCAD and another CAD
system, using IGES. Usually, a one-time translation to or from IGES does not pose
a serious problem. However, data loss can become a concern if drawings are repeatedly
translated in and out of IGES.
Recommendations
Inspect the conversion tables of the IGES translators of both the source CAD program
and AutoCAD. Get to know what entities are supported. Restructure the drawing to minimize
the usage of objects that require compromises and substitutions.
See the conversion table for IGESIMPORT for specific details of the scope of the IGES
translator.
