I'm a paid Fusion360 customer and developer, with more than 6000 happy users of my store add-in.
I get a lot of AutoCAD people asking for a version for them.
Does anyone at Autodesk read this? (If not, does anyone here know how I could reach them?)
I'd like to port my code to AutoCAD (Mac and PC, and any other variants that make sense) as well as Inventor. It's a big job (way more than 30 days to complete - my codebase is huge).
Is it possible to get a license to install the above products, solely for the purpose of development and customer support, without charge?
You got the answer in your other/same post,
