  5-fold symmetry?
Posted by: Peter Blomberg - 2025-08-22, 1:47 - Forum: Parts Authoring - Replies (5)

I'm working on the duplo flower with 5 Leaves and Top Stud 84195. I've fixed most of the issues with the original mesh, but...
I don't know if I should submit it as one part or subdivide it into 5 (10) repeatable subparts. One of the challenges is rotation. The original mesh is not aligned with any axis (see top view in picture), so it would be very difficult to create clean symmetrical breaks (normally I'd use the mirroring over an axis). The angle of rotation between parts would be 72 degrees, which would require six decimals in the transformation matrix. Given these challenges, would it be acceptable to "ignore" the 5-fold symmetry and just not subfile at all?

  Parsing LDraw
Posted by: Max Murtazin - 2025-08-20, 18:04 - Forum: Help - Replies (3)

*sigh*

Okay, I've probably been it at it many times and probably even asked some questions on this topic before, but, alas, I'm at it again - trying to build an LDraw file format parser in C#. Why C#? Tl;dr: I need it for other stuff, and that stuff uses C#.

Well, the question itself: How does one even go around effectively parsing LDraw? This topic is a bit confusing to me due to the recursiveness (I guess that's what the word would be) of the format. My current approach is like this:
1. Read through all of the file, store all the faces in an array, store all the submodels in a separate array
2. Go through the submodel array, go to step 1 for each of them
3. Once the process is out of this recursive mess, "resolve" each submodel by applying the transform to it's triangles and adding them to the submodel's parent
4. Done, I guess?

It is very simple and doesn't account for, like, any meta or other stuff that could be important, but it should be enough for the start. I'm just not sure if this approach is good, or how it possibly could be improved

Also, I know I can read stuff like LDView source code, but I'm really bad at reading code made by other people, so it would probably take way more time than just asking it here

  Duplo drawer height
Posted by: Peter Blomberg - 2025-08-19, 7:51 - Forum: Parts Authoring - Replies (4)

It seems that the duplo drawer 4891 is 2.6 LDU too high compared to physical part. It doesn't fit the 52 LDU slots in cupboards.
https://library.ldraw.org/parts/9776

Furthermore, the origin seems to be 3 LDU above the part. Can we live with that?

Hi all,

Why is the angle of the arrow tip on Minifig Harpoon 57467 not straight?
It seems at an 11 degree angle?

  Filepath Backslash(\) or Forwardslash(/)
Posted by: Hageta - 2025-08-18, 15:16 - Forum: Parts Authoring - Replies (6)

All the documentation I found used backslashes(\) for filepaths e.g "s\subpart.dat". But I could not find if forward slashes(/) are also allowed. LDView can use either without any errors, while LDPe does show an error. If either both or only backslashes are allowed it should be mentioned in the Documentation either under filename or a new section. I do ask this because in ConvertToLDraw I currently use forward slashes and I got this Bug report. I will change the filepaths if they are out of spec.

  Part Tracker search

Is there any way to search for unofficial subparts that have at least one official parent, but do not have any unofficial parents?

Hi there! I am looking for the pieces mentioned above. I've tried designing them myself, but I am simply too inexperienced with getting the printings onto the pieces and such. Help would be greatly appreciated, and if not, i still appreciate your consideration Smile
