How many people use cinema 4d software for interior designing and architecture work?

Actually, I never met any person who is using cinema4d before, even when I'm browsing the3d forums rarely I found, I believe that3D MAX or Sketch Up with Vray render are on the top.

People tend to use3D Max or Sketchup more often for Arch-Viz because most Companies and most Architecture Universities and colleges Use them, i don't think there's really any advantage that those two have over Cinema4D when it comes to actual production, specially now that there is VrayforC4D plugin that works the same as Vray for any other software
