Big shout out to the LDRAW community and Roland Melkert for LDCad! And Rebrickable!
I trained a machine learning algorithm to recognize pictures of bricks, using an animation I made in LDCad. With a parts list from Rebrickable. And parts from LDraw of course. 
My ideal scenario is to grab a handful of bricks, toss them on the table, take a picture, and have the program catalog the pieces.

I put all the how-to details in an article on medium. https://towardsdatascience.com/machine-l...12e0544012
I am working on some other ideas for machine learning brick projects. And it would be cool if people have feedback or wanted to collaborate.

I updated the new LDRAW ALL IN version. There is no problem in the modeling by MLCAD. But when I run the POV file exported from LDRAW, the wrong message is as below.
I checked the before POV file made by old LDRAW ALL IN version, there is no problem. I don't know if there is any option need to setup. Thanks a lot.


Parse Error: No matching } in ‘texture’, undeclared identifier 'lg_gold_chrome' found instead

I'm starting to write my own parser that will convert an MPD file to JSON format.

Are the FILE, Name:, Author:, !LICENSE, ROTATION properties case-sensitive? Will they always be the same case as I typed them or should I ignore case?

Thanks.

In case anyone has wondered what happens when you accidentally double click a part in the parts bin after a Select All:

   

I know I have posted this before, but I've been making the Datsville HD render more interactive.

You can click on the buildings (only one so far) and a popup blurb will appear with a message from a Datsville resident.

Not sure how much further I will go with this. It depends on how much I can automate the process, since I plan on making further revisions to Datsville itself too.

I found a measurement discrepancy in set 21004 between the LDraw version and the real thing. I know that sometimes things don't work out precisely between the two, but in this case there's a mismatch of exactly 4 LDU, and I'm trying to pinpoint why.

This involves the rotunda section with its stacked 6x6 dishes and 4x4 round plates, and the 6L axle that supports it. Here are the precepts:

• The 6L axle has a length of 120 LDU, nominally equal to 48mm in real life.
  
• As we know, plate height is 8 LDU (12 with the studs), so two stacked plates are 16 LDU high (20 with studs).
  
• The center of the 6x6 dish has the ordinary plate height of 8 LDU, and the cavity adds another 8 LDU, making it equal to two stacked plates in height.
  
• As a result, the 4x4 round plate sits entirely flush within the 6x6 dish.
  
• Per the instructions, and confirmed in the physical set that I own, the 4x4 round plate at the top of the assembly sits fully within the uppermost 6x6 dish, and the bottoms of both that dish and the 4x4 dish should be at equal height.
  
• The axle hole in the 4x4 dish is 12 LDU deep.
  

Dear LDraw.org member!

I am learning how to simulate lego set. I tried with LDCad with its script.
I think this is the best simulate for lego set now. 
But, I saw in youtube that they can simulate lego set with Solidworks.
So could you give me some advice, how to import LDCad file to Solidworks?
Thank you! 


This video using SR3DBuilder. But the Developer was pass away some years, and now I cannot install it in my PC window 10.

Could someone with Visual Studio installed compile the following program please?

Thank you.

Guys,

I'm working my way through:

https://www.ldraw.org/cgi-bin/ptdetail.c...288c01.dat
https://www.ldraw.org/cgi-bin/ptdetail.c...288c02.dat

and would like to know if someone has pictures of the variants.

Type 2 should have a hole at the rear.
