wdupre is absolutely right. Let's use MS Word as an example. If you create a document (such as a novel), you own that content and have full copyrights, etc. to it. There is no question that the novel belongs to you and not Microsoft. However, the DOC format itself is owned by Microsoft, just as the PSD format is owned by Adobe, the 3DS format by Discreet, and the 3DM format by McNeel (Rhino). I own the ships I created using Rhino, but not the 3DM format. This is why the EULA clearly states "file FORMATS". Yes, the CL file formats are readable in a text editor. This in no way means they are the same as a TXT file since they contain proprietary commands and parameters laid out in a very specific manner. Anthony Hernandez Curious Labs
