I'm not familiar with the train and rail parts.

What is a good distance to separate two parallel rail lines from each other? Taking into account curved rail sections and the general way rail parts are supposed to be connected.

Currently I have them set as close as possible next to each other. I chose this value because part 949ac02.dat splits into two lines spaced this much from each other. But looking at Lego.com's TRAIN TRACK PLANNER it seems this can vary.

Sometimes I am also looking for new possibilities for creating pattern.

One of the challenges I am faced is to reduce the colours used in that pattern. This is mainly necessary because most (if not all) pictures are antialiased and therefore we do not have sharp edges that we can work with, if we try to automatic the generation of pattern in ldraw file format.

I tried it so far with an algorithm from bitsticker project:

I wish you guys a happy and playful new year 2014! May LDraw keep going strong.

Has anyone used Yafaray to render models? Supposedly it is faster than POV-Ray at rendering complex images with a lot of features.

Does Yafray have a scene description language like POV-Ray? Can it be run standalone without Blender? Or is Blender also required?

Can someone modify this so it's three lengths, 48 studs wide, while duplicating the bottom holes threefold?
Also a variant where it is 32 studs wide?
Thanks.

Recently I've noticed that Chris has begun to hold certifiable but currently unneeded primitives (for example this one). To me, this seems like a bad idea.

According to our reference, we define a held part as:

Reference Page Wrote:Hold (No) - It's getting there, but not yet.
There are errors to be corrected before the part can be released. The author has to take care of the errors.

Download it here:

Most changes since the previous release are "under the hood". I made the file headers uniform and filled in missing information. I de-inlined a number of sub-models. I made sure only parts used the DAT extension. There should be no change in outward appearance, so the previous town map still is accurate.

Here's the project's Facebook page:

Many LEGO pieces have "LEGO" molded on every knob. (I think it is with every solid knob which seems to affect "System" pieces as opposed to "Technic" pieces.) In fact they happen to have other things molded as well but those are usually hidden and very across the same type of piece.

But it seems to me that LDraw somehow doesn't include that. Or at least not as "first class citizen". MLCad doesn't show such molds at all. LDView does.

So how is that stored? Judging by how LDView shows it it is not part of the 3D object but rather a "texture" (that would also explain why MLCad doesn't show it).

Why is it so? Would that be too complex to model that as well? Or is it just for historical reasons?

I surly do see potential opportunities. General building guidelines forbid some constructions as they stress the pieces too much. Among them are such that are allowed with pieces without molded "LEGO" and disallowed with others. Having the "LEGO" in 3D model would allow automatic recognition of touching edges (and thus unadvised build).

Hi,

This is a rookie question :-)

I have created a simple model in LDD 4.3.8. The model base on EV3 set (31313). Because I don't like the format of building instructions from LDD, I wanted to try LDView and LPub. So I have done an export from LDD to LDR file.

I have installed LDraw_AIOI_2013-01_setup_32bit_v1.exe , plus the latest complete.zip and ldrawunf.zip . I run LDMakeList.exe as well.

When I try to open exported LDR (attached to this thread) in LdView, I get below errors:

This thread is intended to collect queries for help needed by parts authors on the parts tracker.

People owning certain parts, please check this thread from time to time to see if you can help us!

We need your help to be able to solve some of the problems of files on the parts tracker.

For example, a scan or photo of some real life part might be required.
