I like that it gives me options to edit my plans which are already created or uploaded from other software, so for example if you have an existing house design saved as a drawing file (e.g.
dwg) then you can open this up within project reader and make changes to what's shown via 3D model view of same drawing. There is no option to upload new drawings/files into project reader however there should be because we use it all day every day! It would also be nice to see how much time has been spent viewing each drawing with progress bar showing where exactly along way through the process.
