	In terms of the history of the file format, changes were (and continue to be) introduced with each new version of ACIS. The file specifies which version it was created for, so the format is backwards-compatible.		In terms of the history of the file format, changes were (and continue to be) introduced with each new version of ACIS. The file specifies which version it was created for, so the format is backwards-compatible.
		+
		+	Though it is readable in plain text, the file format does not lend itself very well for editing. Objects represented through the file can be quite confusing. For example, if you wanted to create a cone, you need to provide some arguments to the cone entity, but what those arguments are is not very clear. This format should mainly be edited through the ACIS program.
