So, what do you as part authors think? Should T-junctions be avoided in
order to avoid the rendering errors that they can introduce, or should part
authors continue to strive to make parts with the fewest number of polygons
possible?

I try to minimise file size whenever possible myself and have nothing against
T juctions. While the gaps can be annoying I feel that they are a fault of
the rendering program rather than the parts.

I’d really appreciate it if you didn’t blame it on the rendering programs.
There’s really nothing that they can do to fix the problem. I can understand
why you might feel that they are at fault, but it really isn’t true. As such,
you might want to reconsider your position. (You might not, and that’s
perfectly valid, but if you don’t, hopefully you will at least acknowledge that
the renderers aren’t to blame for the artifacts; the T-junctions in the part
files are to blame.)

Then break up the offensive T-joins automagically and render it perfectly. (...) (18 years ago, 6-Mar-07, to lugnet.cad.dat.parts, FTX)
