A fresh list of "most common" parts missing from LDraw (and a "Thank You")

[tom alphin]

I just want to start by thanking the community for making tremendous progress adding many of the Most Common LEGO Parts to the LDraw database.  In talking with Orion at BrickCon last weekend, it became clear that the group has made great strides to increase efficiency in many ways, including clearing out the backlog of unofficial parts, as well as extracting new part shapes from both Unity, the Builder App, and other Unity-Based app sources.  This is awesome work!

For example, tons of the parts highlighted in this earlier thread are now in LDraw.  (Most notably, the last part in the top 1000 which was missing was DUPLO 3×3 Flower (Part 84195) - It was added in the past month and is now in my parts guide with a nice image!)

The good news is that there are just 87 of the top 2000 parts which are still missing! That's a lot better than I saw a year ago!

P.S. This is a manually curated list.  I have checked Rebrickable to ensure that LDraw doesn't use a different Part ID, and I've checked the forums to see if the part is in progress.  (Previous attempts to automate this list weren't as useful.)

Would it be helpful to break into two lists - one list for parts which can be found on the Instruction App or Unity, and a second list for everything else?

Certainly. Didn't look through the entire list, but if it contains decorated parts (prints/stickers etc.) those should likely be separate as well.

Are there parts in LDD not found in Unity/BIA?

[Orion Pobursky]

Tom doesn't include printed parts in his parts guide.

Are there parts in LDD not found in Unity/BIA?

Yes, I just split it into two lists... 

1. Parts likely in Unity/BIA
   
2. Parts which might not be in those apps.
   

Both are important, but the first list will likely be easier to implement!

Tom doesn't include printed parts in his parts guide.

👍 There are plenty of resources to learn about printed parts.  I'm simply trying to create the best resource to learn about the various parts themselves (part shapes/moulds).

[Gerald Lasser]

All but one part (73766a) are available through the BI

Here's the overview

That's fantastic news - it seems like it is a lot faster to get parts added to the DB when they already exist in the BI App!

I did see about four parts which might already be in LDraw... I will update by unofficial files and look for them this evening.  I will remove them from the list once I've added to my guide!
