Siemens makes CAD packages. Dassault too. Autodesk does nothing but CAD packages. All in the top 20 of "software companies by revenue". PTC is number 42 and Bentley is 70 again CAD packages. It might be a niche, but it's pretty expensive niche then. Pure CAD companies Autodesk, PTC and Bentley made 2,5 billion dollars of revenue in 2014.
