I’ve found an error in the description in the official part file ‘63869d01.dat’.
This is not a ‘Technic Beam 15’!

In the unofficial part “6221805k.dat”, the files “logomicht02.dat” and “logomichb05.dat” are missing.
Likewise,
the file “s\6177973rs00.dat” is missing from the unofficial part “6177973r.dat”.

Various Speed Champions sets include a Formula 1 helmet (7071.dat).
Unfortunately, I can only assign a color to the helmet itself, but not to the visor.
I haven't been able to find a solution on the forum.
Is there one?

I'm very new and definitely not versed in this community, please disregard my ignorance and naivity as a noob.

A story: I build the 6398 Police HQ in Studio for nostalgia; upon rendering it the blue webbed dish looked a tiny bit angular, lacking angular resolution. I dig deep, how parts are made, how this LDraw works, tried LD Part Editor, used spreadsheets and ultimately "updated" the 4285s01.dat sub-part. I tried my best to keep CCW orientation. There are minor coplanarity issues with it (can't spot it on renders) and I can't comprehend command line 5, so I did not touch those.

If someone has the time to take look at it, have the knowledge and will to correct it (if needed) would be nice, especially if this could become an official part later on.
Part attached to this post.

  1. To fill in the gap between a standard-resolution curved primitive and a 48-resolution curved primitive
  2. To fill in the gap between 16-sided geometric curve and a 48-resolution curved primitive

I know that it is being used in situations that match option 1 above. I don't know if it is being used for option 2 or not. One (relatively minor) problem is that option 1 is incompatible with how LDView does primitive substitution when the curve quality is set to certain settings. I should be able to fix this. But there is no way for me to generate the primitive in a way that is compatible with both option 1 and option 2.

For option 1, the resolution of the inner part needs to track my primitive substitution curve quality, and the outer part needs to track the 48-resolution version of the same thing. When the quality is set to the default value, this would be 16 and 48. For the next notch on LDView's quality slider, the 16 becomes 24. Right now, the 48-resolution version remains 48 at that setting. (That would probably change. The next notch uses 32, and since 32 doesn't evenly divide into 48, that would have to change. Same for the next notch, which is 40. An easy solution is to use 64 and 80 for the 48-resolution version of those two notches.)

But if this primitive is used next to hard-coded 16-sided geometry, then the inner resolution would need to remain 16, no matter what the curve quality is set to. The current description for the aring primitive does specify that it interfaces between high-resolution primitives and normal-resolution primitives. So does this mean that interfacing with 16-segment geometry is not allowed? If so, I can make it work (although it will cause my primitive substitution to render more geometry for 48 curves when the curve quality is set to use 32 or 40 segment curves).

If it is used next to 16-segment geometry, then I feel that that needs to be forbidden, and a new primitive needs to be introduced to fill that (different) role.

Side note: for POV export, the first version of this primitive is no geometry at all. The second version is a chord.]]>

A) To match the size of the BI original, the handle primatives of the bar needed to be scaled down by 10% in one direction is it OK to do that?

B) the support beams for the bottom tube. BI just has them clipping into the geometry of the tube which isn't great obviously. There are primatives for if the support beams are at the bottom of the tube but there don't seem to be any for if they are at the top? So is there a subpart or something I can use?

C) The origin for the part doesn't seem right so I was wondering where it should go? I mean yeah I know I need to adjust it so the mirroring will work properly but I want it in the right place.

So do I

A) make a jillion tiny quad boxes in white and red respectively
B) Make them diagonal lines instead
C) Make the rays pink since thats the average between red & white
D) Ignore the stippling entirely
E) Some other solution like making it a texture instead
