I know this is an older thread but I think my concern fits very well to it's title.
I came across that the two torus primitives "t04ounit.dat" (as an outer regular torus primitive) and the reverse ratio torus primitive "r04o1000.dat" are essentially identical.
Also a major radius to tube radius of 1:1 couldn't exactly be called reverse. So in my opinion the "r04o1000.dat" would actually be redundant and therefore obsolete.
I investigated further, that the "r04o1000.dat" is only used in 2 official parts ("6797.dat" and "56554.dat") and 1 official subpart ("11459s01.dat") and apart from that also in 1 unofficial part ("34172.dat") and 2 more unofficial subparts ("2715s01.dat" and "34172s01.dat"). That's all up to now with regard to the latest (un)official LDraw parts collections (http://www.ldraw.org/library/updates/complete.zip and http://www.ldraw.org/library/unofficial/ldrawunf.zip).
So there are all in all only six available files where this part is actually used and where the "r04o1000.dat" could just be replaced by "t04ounit.dat" and I litterally mean just a word find-and-replace is enough and everything is fine and we can get rid of this unnecessary part.
What do you think?
I mean I could do that in a wink if you want but I'd like to avoid a new and absolutely unnecessary recertification process for these few affected parts.
And a new certify process would be obsolete because it wouldn't actually affect these parts in any way as these replaced primitives are really absolute identical.
Kind regards,
Tom
Thanks for pointing this out. Revised files are now on the Parts Tracker replacing r04o1000 with t04ounit. However trivial the change to content I'd prefer them to go thorugh the certification process, but hopefully this can be quick. I have also removed r04o1000 from the primitives reference webpage.
