It's been a while, but as I see it, the initial question is still unanswered. I would like to repeat repeat the question and to specify it, so maybe someone can validate or correct me. I'm using Autodesk CFD and AutoCAD 2015 with an educational single-seat license. In the "LICENSE AND SERVICES AGREEMENT" it's said that it can be used for educational purposes only, which is specified as "purposes related to learning, training, research or development." but not for "commercial, professional or any other for-profit purposes.". So, where does learning, training, research or development turns into professional use(which is not further defined in the document)? Example: The use of the licensed Software for working on my masters thesis for graduation is, in my opinion, clearly an educational use. Now imagine, while working the possibility of a scientific puplication based on my constructions appears. This publication is directly connected to learning, research and developement, non-comercial (from the viewpoint of an institute at an university), non-profit (except for scientific reputation). So is this a 'professional use'(I'm not getting paid for my work of course, since it's part of my education)? What about co-authors who had nothing to do with the actual construction but were involved in the research? I'm interested. With best regards, H. Müller
