Many designers like to feel on top of their projects, virtually and figuratively. Using images like this during design development might work for office politics or designer-builder relations, but what end-user ever encounters a site from this angle? Once it's built, it's a little late to say "gee, the parapets are out of proportion" Tracking a project via elevation, perhaps with figures for scale, may miss the dimension of depth, but it does approximate the user experience more accurately than the above type of view.
3D modeling is now so well-embedded in building industry software, it's easy to periodically examine the appearance of a project from the user's eye level. Unless the designer does not know how to request a specific view from the software. It's important for design students to understand the basic geometry of linear perspective, since any 3D modeling software is built on that geometry. At least for now.
