Well, in addition to the header you could also look for a couple of pieces of "user data" that MoI writes to the file to store some of its specific information. The user data will have a particular UUID identifier on it.

You're certainly not going to get any other CAD program that will write out the same combination of header text plus specific user data that MoI generates.

That could be a possibility, but in my experience anything dealing with file format support can easily end up to be a lot more work than initially expected. To do a good job with it usually involves quite a lot of testing.

Also since MoI version 2 has already been released, if we went this way you wouldn't be compatible with the current version of MoI and would only work with a future version I guess...


If you use the other method of identifying a 3DM file that was written by MoI, you would actually be compatible with both the current MoI v2 version as well as MoI v1.
