| Unable to open output file
|| An error occurred while opening the DGN file that you are importing the IGES file into or while opening the IGES file to which you are attempting to export. Error is caused by an invalid path specification, the existence of a write-protected file with the same filename, or other similar condition (command line or batch method only).
| Aborting due to memory allocation failure
|| Sufficient memory to complete the translation is not available. Translating large files can require substantial amounts of memory. Because both RAM and hard disk space are used, you must add more memory or free up additional hard disk space.
