Intention was to use a more VRML like syntax.

I had choosen the name BrickCAD because the system had uses in genuine
construction CAD, not just LEGO(R).
Besides the name BrickCAD has no generic connection to Lego(R). Other than the
use of parts designed by LEGO( which SHOULD be protected from theft, like any
other industrial design) I can't see any issues with a new CAD system. other
than the previous program called BrickCAD with which I have a NO connection.
Parts are seperate issue from a CAD Engine. Cracking down on a CAD engine just
because it happens that it can be used for Lego(R) is non-sensical.
(It would be like a lumder merchant saying you couldn't produce a CAD system
for his timber lengths!). The only concern I confusion I can see is with
AutoCAD2000, (but IntelliCAD2000 exsits) or with the original BrickCAD.
Besides the main aim of the posting was to start disscusion on what COULD be
done in an ideal situation and not nessacirly on an actual implementation.
Importantly I was not trying to design or build a system as competitor to
Creator which is TLG's offical product. Indeed I would be pleased if they used
the comment in lugnet.cad.dev and this thread to develop an improved version!!
(If you are reading Brad, I'd like clarification on the issues you had over
BrickCAD).

Indeed an EDF (Extended DAT format) could prove to be better than a completly
new one. The Object model was intended to be internal to the program though.
