I have worked in architecture and engineering, in various roles from CAD operator to design engineer and project management. I've worked on small buildings I would call 'small equipment shops' to 40 storey residential buildings, large traffic bridges, schools, hotels, etc. I cannot for the life of me understand what bluebeam does that's worth its per user costs. I've worked with companies that wanted me to pay hundreds of dollars per user for the ability to mark up PDFs...when I can just mark up the PDFs without bluebeam. Massively overpriced nonsense as far as I can tell.
