You're both right.  A perfect representation from 3 view using just an outline 
is impossible.  Imagine a sphere.  All three images would be circles.  If you 
intersect 3 orthagonal cylinders, you get a shape that would give you your 3 
circles, but it wouldn't be a sphere.

That said, a script that did the orthagonal extude and intersect trick would 
work for many shapes and might give a useful starting approximation where it 
doesn't.

I saw a somewhat related Blender tute where a person recorded himself sitting 
in a spinny office chair.  He paused for a few sect every every 10 deg (IIRC, 
he used a protractor with holes drilled in it and a wire taped to the chair's 
base).  He used this as a backgound image and traced the outline while 
rotating the mesh to match his position.
