This is a table summarizing the IGES entities supported by this product.
IGES files have the extension *.igs or *.iges. This table lists the IGES entities supported for import. The supported IGES versions are 5.3 or earlier.
After importing an IGES file, and before running a Fill+Pack analysis, pay close attention to the edge length of the mesh around high curvature areas on your model, and make sure they are not too coarse. It is recommended that you mesh with a smaller edge length, allowing the mesh to approximate the corners correctly.
The following table lists the IGES entities that are recognized and translated when reading in an IGES file. If the IGES file contains entities that are not listed here, they will be ignored in the translation process.
