[Bf-funboard] Question about projection

We have an Ortho button for cameras.  Just yesterday a need to do an 
isometric projection (specifically a cabinet projection where X-Y are 
mapped to a plane parallel to the camera image plane and Z is mapped to a 
constant angle in that plane.)

Begin Fixed spacing font:

     /        /|
    /        / |
   +--------+  +
   |        | /
   |        |/

End Fixed spacing font.

Is such a projection theoretically possible to implement in something like 
Blender?  Or is the math required so skew from the "normal" projection math 
that  it should be left to the domain of  CAD progs?

Such projections are used extensively in patent drawings for example, and 
my boss offered my services to her Dad who is a patent attorney.

No mater how I tried to simplify the shading, it wouldn't satisfy 
him.  "It's too much like a photograph.  I want it in 3D, but I don't want 
it to look real."
