Dunno if CAD packages count here, but I wrote one in 1981 / 82
called 'KDS 5000', for designing and costing kitchens :-)

It used its own DOS, with a modified RWTS driver, and the 3D
perspective stuff used 32-bit binary multiplication (coded in 6502
assembler) and 4*4 matrices to do the object--world--viewport mapping.

The shape database used indexed-sequential files to hold the
virtual plot instructions (vectors), mapped thru the matrix pipeline
to either the screen (in hires monochrome mode) or a Watanabe
flat-bed plotter using the Aristocard (a printer card I designed for
a UK Apple dealer in 1981).

Still got a Europlus up in the loft (haven't booted it up for years though)
