Hi.

While preparing new instructions for one customer I found a rubber arrow helper really needed. So I created one and want to let anyone use it.
I got an inspiration from the arrow helper thread and holly-wood.it and Technic Flex Cable - so you can see I'm _not_ experienced with these LDCAD meta commands. Please, check if this is correct way how to create such arrow. What I see in LDCAD is that sometimes a gap between the end segment and a rest of arrow appears, for shorter arrows one need to shorten the "tension" of path points. Otherwise it looks good, as far as I can see. What do you think?

Then, what about to cooperate on creation of one section of arrow helpers together? So far, I found:

* straight arrows of different lengths by Willy Tschager
* arrows for rotations etc. by Jaco van der Molen
* this rubber one by me

My idea is to create a simple zip archive with all these together (including donor files etc.) and LDCAD partBin definition so anyone can find and use arrows easily: in LDCAD and, later, in LPUB3D.
In following LDCAD releases this could be a part of LDCAD distribution as another helper files.

What do you think? Willy, Jaco, Roland?

So far, I use this partBin definition, in templates subdir:

I propose the introduction of these six primitives (3 version 16 sides and 3 version 48 sides) that could solve some situations.
The example I have attached is the one with which I came up with the idea, in fact the most correct use would be for patterns with incomplete rings of different colors.
The primitives I propose come from the classic ndis to which, however, I moved the vertex of the circumscribed square to bring it to the vertical of the last vertex of the circle.

They should be quite interchangeable with the current tang primitives, but reducing the number of triangles required (partly because they are already included in the primitives and partly because their shape is more regular).

Hi, can you tell me how to upload an avatar?

LDView 4.4 is now available.

You can download this release from the LDView Downloads Page.

In my opinion, the biggest enhancements in this release are:

1. Support for DPI scaling (AKA High DPI) on Windows, as well as Retina displays on macOS.
   
2. Support for SPHERICAL and CYLINDRICAL texture maps.
   
3. A new Search field in the Model Tree.
   
4. Support for !DATA meta-command for embedding texture maps into MPDs.
   
5. LDView.com executable in Windows so that command line usage now shows errors (and optionally warnings).
   
6. Support for macOS Finder thumbnail generation (toggle on LDraw tab of preferences).
   
7. Support for macOS Dark Mode.
   
8. Support for Apple Silicon-based Macs.
   
9. Multiple important TEXMAP bug fixes.

This new feature looks interesting and may be useful as a starting point for complex parts with organic shapes.

Hello all.

I have been wondering if there is a way to create a collection of images of a part from different angles automatically.
The only comparison I can think of is to use a Photoshop action to rotate the image, save a copy, repeat that a few times, close the part and onto the next.

I want to train a neutral network to identify Lego bricks on a conveyor, and sort them.  The standard way is to take photos from a few angles and label them.

That could take forever with the dataset I want to create, even using a handful of camera taking photos at the same time.

Does anyone know if this is possible with Ldraw?
I saw that you can go to a predetermined viewpoint and take a screenshot, seems like a good start?

I know a virtual image set won't be as accurate as taking sample photos of real bricks in situ, but I can add real photos to the dataset latter for bad matchups.

Thanks for any recommendations ?

Hi! Can you make me somebody please this terrier dog looks like to Toto dog?

Hi all,
Philippe recently created a number of Scala parts for this thread. I'm looking for another one of these old parts, the standing cat 6175, which has two printed varieties:
