Interpret IGES log files

View IGES log files

The first section of an IGES file typically describes the contents of a file. Each line of this section is displayed on the information line.

If there is more than one line in the section, you can browse the contents of the section after file retrieval is complete by using the prompt history window, or by viewing the comments section of the IGES logfile created by the retrieve process.

Open an IGES log file

Choose File > Show Image.

The Alias errlog file and IGES logfile contain a specific error message for each problem encountered.

Each error message includes the IGES entity type number and a Directory Section line number where the entity occurs. The errlog file is located at /usr/a1demo/errlog; you can browse it with any UNIX text editor (for example, vi or jot). The IGES logfile is located in the same directory as the retrieved IGES file.

Identifying IGES supported entities in log files

Learn more about the IGES entities supported on import by Alias.

All other entities with an entity use flag value (Definition) are ignored by the input translator.

IGES levels

All supported geometric IGES entities that are associated with IGES level are added to an Alias layer. For example, if a 126 B-spline entity’s directory entry indicates that it is on level 42, then it is added to Alias as Layer 42.

IGES ASCII format

The IGES translator imports ASCII format IGES files with or without linefeed characters at the end of each record. Binary IGES files are not supported.
