Hi there,

I've just released an initial version of mpd2glb, a node.js tool for converting from packed .mpd models to GLTF binary format (.glb).

The ouput models are world-size, i.e. centimetres in size, not LDUs, to make them consistent with other non-LDraw GLTF models with different dimensions.

The tool is already available at: https://github.com/anteloc/mpd2glb

Cheers! 

Hello,

With version v1.7 beta 2a, I no longer have the automatic part snapping feature.
Is there a specific configuration for this new version ?

Thank you

Part 4175 currently is 28 LDU in depth, the BI version is 30 LDU. I don't think the part has changed dimensions over the years so it seems to be incorrect from back when it was originally made way back in 1998 - 2008.  I guess it was assumed to be 28 LDU since that would be the expected dimensions normally.

I've attached the latest BI version of the part.

Hi there 

I've just released a first version of an open source web app for viewing LDraw models both on Virtual Reality and web browser, see below for links.

I've developed this in less than a week, using AI (Claude Sonnet 4.6 mostly) for creating a single (big!) web page that works in "web mode" as a visualizer for LDraw models, and also works in VR (Virtual Reality)/MR (Mixed Reality) mode to virtually inspect LDraw models using a VR headset.

Model descriptions and categories are not accurate, I've used an AI vision model for this (qwen2.5vl:3b), to describe image renderings of the models, and it makes quite some mistakes.

For VR/MR, I've tested this with my Meta Quest 3 headset only.

You can give it a try at: https://anteloc.github.io/modelscope-xr.html
Demo video: https://www.youtube.com/watch?v=IhGm3KRSl7s
Source code: https://github.com/anteloc/ldraw-lib

Any feedback is welcome, this is still a first release and there are quite some things to fix, but I think this is good enough already to play around 

Cheers!

So I am having a go at making part 76923, and have done most of it. Just a few things I have a query about.

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.
