Subjects: Extending ACIS, C++ Interface

To avoid naming collisions, the filenames you use when extending ACIS must be unique (they cannot conflict with the names of files existing in ACIS). It is recommended that filenames follow the "8.3" format, which means the name should be no more than eight characters long, plus a three character extension.
