(...) LDAO writes those entries to ldraw.ini. I'm not sure if any other programs update that section or not. The "Oblique" view is the default view for LDraw, and was also used for LDLite (I think) and L3Lab. "UpsideDown" is derived from "Oblique". (...) (24 years ago, 4-Oct-00, to lugnet.cad.dev)

I believe the matrix happens to produce a standard isometric view, but doesn't do so in the traditional 3D graphics way of rotation. This means that in addition to not looking right after rotation, it also doens't produce correct results when you (...) (24 years ago, 4-Oct-00, to lugnet.cad.dev)
