Hi,


I'm using the 3-16ndis.dat primitive in the part I'm working on (35103).


In fact I had to slice a 2-4ndis, so I replaced it by two 3-16ndis and the two quads I get using SlicerPro.


The matter is that, there's a realy small gap between the 3-16ndis primitive and each quad. But this gap disappears when I inline the primitive with LDDP, so I deduced it's a matter of precision using SlicerPro. The problem is that even with a better precision the gap is still here.
I've the same problem with 3-8cyli.dat for the vertical part.


So my question is : should I keep the primitive and the gap, or should I inline the primitive to close the gap ?


Or maybe there's  a third way I didn't thought about...

Hi all,
There we go, my first thread here. It's about LPub3D. Despite my well defined love-hate relation with LPub3D, I still can't figure out how to get a decent BOM of the instructions. Sure, one page works fine, but multiple pages end up to ... nothing actually.
With a big model you have to zoom out to get to the bottom-middle of the BOM to change it's shape. But since the page itself stays in the middle, AND CANNOT SCROLL the page/viewport, you end up with a tine black square that is so small that you can't select it anymore. A solution is to change the shape of the BOM, from 'area' to colums for instance.
But then you end up with a very long list you still cannot resize.
So you split the BOM. Splitting the BOM doesn't take landscape orientation into account and besides this, you work with columns. So the list is split as if the page was portrait.
And so on and on and on and....

How do you make a BOM that:
- can span multiple pages
- splits at reasonable points
- does not jump to an different/arbitrary) location if you resize, move, split or change its shape

Has anybody success of making a BOM in LPub3D that didn't take hours and hours and didn't had to, after using one A0 page, use Photoshop to make things easier?

I realise and concur that the author of LPub3D did a great job. But that doesn't take away the fact that I'm starting to hate building MOCs I cannot publish.
My advice to LPub3D is therefore, stop making exotic features work; work on functionality and reliability. LPub3D crashes way to often, and I hate, as a law abiding citizen, looking at a blue turning cursor idicating that the program is busy. Well, it's not.

Note. As you can see, I'm having trouble not to reflect my frustration. Yes I'm thankful for/yo people like Sandy. But LPub3d is not only consuming way to much time, it spoils the fun of being an AFOL too much. We're here to share our love for and involvement with other LEGO fans, not to bug-fix some appliaction.

Ciao, and thanks in advance,
Eef

Is there some sort of "flood fill" utility to triangle-ize the blank space in a pattern (up to a defined bounding rectangle). Filling in the negative space with color 16 triangles is super time consuming. 

Maybe this exists and just to dense to find it.

I would like to request a simple tool to randomly distribute objects (such as trees or bushes) over a wide area, taking into account collision with other objects and the ground. I.e. just drop them vertically from the sky and make sure the trees 1) don't intersect with each other and 2) stop falling when they collide with other objects below them such as bumpy terrain. If the tool runs from the command line that is okay! Thanks!

I've started to model the 42125 set, and I have a problem with the front hood. This one is a 5-bar linkage, not so easy to create directly in LDCad. I created a Geogebra model that easily gives me a solution, but when I bring the values in the model the hood is placed very low and there is a collision between the hood and the chassis. I think I verified correctly all the assemblies, so I'm puzzled... That's probably a big, obvious mistake, but...

Who has this part? Could someone please check this geometry:

And check the pin hole?

It's my understanding that these two parts actually represent a single part with a two-sided design, rather than two parts with distinct designs. Should they be merged? and if so, under what number?

Hello! I am an academic researcher leading a project to teach AI agents how to assemble and disassemble Lego models.  So far we have built a learning environment that exposes certain basic operations (adding/removing/moving bricks), and now we are looking for data!  We have already taken a look at the OMR (amazing work!) but would like to include as many model files as we can get our hands on.  I see that there are many files posted to various forums here, but we want to be good citizens, ask permission and not just scrape everything in sight.  With that in mind, I have a few questions:

A. Is it OK to write a script to crawl these forums just to find what's out there?
B. Once we have a list of what's out there, can we reach out to individual authors seeking permission to use the files in a way that isn't spammy or obnoxious?
C. Anyone reading this who is excited about the prospect of Lego building AI agents and has any reproductions of official sets or MOCs (or really any .ldr or .mpd files) that they would like to share with us, please get in touch, we would love to have this data!
D. If anyone has any suggestions of other forums to check out or better yet, bulk repositories of public model files, we would love to hear about them.  We have done some poking around, but I'm sure there are things we haven't found yet.
E. Are we correct in assuming that we can use the OMR model files as long as we abide by the attribution terms of the relevant creative commons license?

Details on how we will use the data:

A. We would like to be able to publicly share a bulk collection of these files with other researchers so that they can reproduce and improve upon our work.  This is important, and one of the main reasons we want to be careful and get permission from the authors of files that don't already come with explicit licensing information.
B. We will abide by all existing licensing terms that come with any content we make available.
C. When we release data, we will prominently feature attribution to the original authors of all included content (unless of course an author explicitly asks us not to attribute them).
D. This is an academic science project, and we will not use the data for commercial purposes.

We are very excited about the potential of Lego + Machine Learning, any other thoughts and suggestions for data collection are of course welcome.  Again I want to stress that we want to be ethical in how we gather data, and will do our best to do right by the community.  We know this material represents a lot of hard work, and we want to respect that effort.  Also, while our team loves Lego, we are all new to this community, so if there's a better place to post this, or if there is any way to improve how we go about this, please let us know.

Thanks!
