IIRC (this would be from e-mail he sent me that I almost certainly no
longer have,
and is stuff I know because I was making an attempt to port it to a
Windows version):
- It was LEGO Germany
- The dispute was over TLG's rights to "studded trade dress" (my take on
it was that his output looked TOO close to instructions -- especially
his solid colored stud sides)
- I don't think he ever shared the exact correspondence (at least not
with me <g>)
- The episode did not cause him to leave the net, instead he decided to
redo his
app to be more generic, renaming it btopia (for Brick-topia) and making
it more
generic so it supported non studs-up-only constructions. I didn't like
the
new version much, it went to the same units in horizontal as vertical,
rather
than scaling properly for LEGO brick units for you, and it never really
improved
much over BriCAD 0.75...
- He ended up dropping btopia once he graduated college and get a Real
Job,
unfortunately.
- I asked him at that point if I could still get the BriCAD 0.75 sources
from him,
but he said he no longer had them; though I would have been welcome to
them.
I don't have btopia sources either.
- The original version of BriCAD (0.2, I believe) was developed on the
Amiga.
It chewed up Chip RAM at an incredible rate. I had a copy of that
executable.
- The version most of us knew (0.75 +/-) ran under Linux, using
X-Windows
- The app was really cool, the first of its kind, and looked really
really
nice; but Carsten was a student when he wrote it, so it had some
learning-curve
"features"
- Take the previous three points, combine them with the facts that we
wanted
the source to compile to multiple platforms and have identical features,
and it
went into high flux when he decided to rearchitect it into btopia, and
you can
imagine that the Windows version never really got anywhere. I was
waiting for
a stable release of btopia that never came, and it didn't seem worth it
once he
quit the project since I didn't like the way btopia had changed (he
actually pulled
some features out to redo them, and they never got added back).
- I didn't think in the end it was too bad, since LeoCAD came along, and
it
was far superior, IMHO.
