This is as much of a Math question as it is a Programming issue, but I thought I'd put it out there.

I want to map X,Y,Z (or Width,Depth,Altitude) to isometric, civil-engineering type 120 degree view. That's the graph paper with triangles instead of squares; I think there could be a trig conversion or maybe a GDI+ matrix transform that would work, but I can't wrap my brain around it. I'd appreciate any help with this challenge.
