The following file on the PT has different connection points compared by the LDD parts.

Please have a look into the appended mpd file, so you can see what I am talking about.
As Tim already wrote - we are free to change. As i do not own this part, I can not decide what is correct or not.

This morning I looked through the files that are on hold on the PT.

My personal opinion on releasing parts is - good enough! - because of the following reasons.
1) Very seldom a part is visible in a picture in a close-up. So tiny errors are not visible.
2) If the parts are on the PT they are used - so they can't be that bad.
3) If I need a part and it is not in the library I am disappointed. If that occure too often i lost interest.

What is good enough!
1) Connectivity portions needs to be on the right place.
2) The origin is placed according our agreements.
3) The parts shape follows the visual appearance of the real part.

What should not be a reason not to cert?
1) T-Junction on flat surfaces.
2) Overlapping flat surfaces on opaque parts
3) Missing of some condlines that do not affect the overall appearance.

So do not wonder if I cert a part where you say - so many errors in the file.

I hope lot of you can follow my thoughts and on second iteration on the PT we can make the parts perfect.

Hi again,

I was wondering if anyone had made any progress with this door piece - see Philo's comment on this page:
http://www.ldraw.org/cgi-bin/ptdetail.cg.../2924b.dat

Thanks

Hi again,

I'm looking for this piece in LDraw? It's a relatively new piece, featured in sets 6864, 7600, 6863, 2507, 2505, 7199 and 9449.

Here's a picture of the part:

Thanks in advance

Hi folks,

I noticed that Batman's cape is now available in Lego Digital Designer (LDD). Please refer to the LXF file for set 6864 here:
http://www.brickshelf.com/gallery/ADHO16..._chase.lxf

I was wondering if someone could use the 3D capture technique to turn this into a LDraw part (using 3dvia Printscreen?)

Thanks

Reuben

I’m making a model in MLCad (3.40 if that would matter) and I need a rubber belt in it.

It is just a simple use: a Technic bush 1/2 (#4365a) placed on an old 9V motor (#2838c01) and connected with a belt to Technic wedge belt wheel (#4185) directly above it. And I find it really difficult to get the position and size right.

I found here thread titled “Rubber bands” in which most important (for me) was another link to page “Modeling rubber belts”. The page indeed helped by providing radius of the Technic parts so now at least I knew what to enter for “R1” and “R2” in “Rubber Belt Generator”.

But how should I know what the dimensions (“X” and “Y”) are? Luckily X is 0 in my case. But the other? How do I know on which height an axle/hole is within Technic brick? How do I know on which height motor axle is placed? I guess that to the difference between centers of those axles I should also add both radius to have the height?

Then after solving that how do I know on which position to place that rubber belt so that it aligns well with the Technic parts?

Is there any software to just point two parts (likely limited to some small set of supported parts) and have a rubber belt connecting them generated?

What I find disturbing is that this is entered not as a “Part” but “Belt”. Is it something specific for MLCad? Will other software be able to “understand” that?

Are there any “predefined” values (in particular for rubber belt thickness) of the “standard” LEGO rubber belts like K3 and so on?

I just can't get this to work quite right. I like to use LDD as a starting point for just playing around with new model ideas. It's quick and easy to just throw bricks in place. But then I want to take that into LDCad and break down the one single model into a collection of submodels in a .mpd file.

I can create new submodels in LDCad. I then cut and paste the selection of bricks I want from the existing single model into the empty submodel I just created, making sure to remove position and rotation information as I do so. I'll then take the submodels and "recombine" them into a new main model, this time made of the submodels instead of individual bricks. I can close and reopen the file at this point and everything is fine.

However, if I then go in and add Steps to the submodels I run into a problem. It's not apparent right away. I can create the steps and page through them and it looks fine. But if I close and reopen the file I'll find bricks have moved to different locations. Some are even part of different submodels. I can't seem to figure out what's causing them to move like that. It's definitely a result of adding steps to the submodels.

I can replicate this with any model I make, whether I start in LDD or even make the whole thing in LDCad. I can split a single model into submodels. But as soon as I add Steps to the submodels, the position of random bricks gets messed up upon reopening the file.

Hi everybody,

i tried to get used to LDraw by hacking 10350p01 from Philo to support another pattern for the black horse (with brown biddle and without white blaze)

I finished one side now, get rid of all BFC-errors and now asked myself what is the next step? I hope it is ok to add several question:

- Do I need permission to post the modified 10350p01 as a new number to the Part Tracker?
- What the proper name of the part - 10350p02?
- What would be the proper author name and history of this file?
- Is there a possibility to mirror the other side or do I need to manipulate the other head side too?

Thanks in Advance

A lot of the images on this page http://www.ldraw.org/cgi-bin/ptpatterns.cgi cannot be displayed. This affects all types of parts, and seems to happen after the files become official.

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.
