There is just an actual discussion on the part: http://www.ldraw.org/cgi-bin/ptdetail.cg...47326c.dat that I like to have here for future reference.

Some years ago we where talking about british vs. american english for part description.

If I remember correctly we decided to use the british english to honor James Jessiman as an Australian guy.
Therefore the meta command is f.e. !COLOUR and not !COLOR.

Now I am aware that the decription of the colours in the LDConfig.ldr is not made this way. There is often gray instead grey used.

If I am right and this is our current policy the LDConfig.ldr should immediately be updated.

Also in our document for part authoring this detail should be mentioned.

I really have my problems in idealisation of this pattern like requested http://www.ldraw.org/cgi-bin/ptdetail.cg...004p07.dat.

Here is what I came along with the picture provided by Steffen.

Is this really better than the previous?

The recently uploaded Mini Snake brought the idea about preventing (auto-)connectivity issues of LDraw related software. The part contains an simple underside stud, but none of the existing stud primitives can be used without a lot of tweaking of the original part shape (see comment about stud4o.dat).
The basic idea is to "convert" the 4-4cylc to a new stud primitive, and then use it instead of the cylc. This step is not forced by the LDraw Standard, but the more i think about it, the more i'm convinced that this last step is worth to be done. If it becomes official, i doubt it will ever be done.
I attached the prototype of that new underside stud. As i have no idea how to name and describe it, help me please to complete it.

Greetings,

I've just recently written 4 different translators for both LDRAW (.dat) and LDD (.g) files that can write to SolidWorks, Inventor, DXF and LDRAW. This was the result of some issues with the previous DAT2DXF translator I was running into with some bad .dat files and other requests that I have seen on these forums with regards to wanting SolidWorks and Inventor translation. I've attached a video showing how these small applications work.

Below are the links to setup files for each application. Unfortunately, I do not yet know how to create a trusted certificate for my ClickOnce Installer, so you may get a warning when downloading. The link will install the application to your Start Menu in SolidPerformance -> BrickWorks -> Application Name.

There are some requirements as of now, though because I am using ClickOnce, I could possibly rollout an update to support older version of the limitation listed below.

Does not support Windows XP and older.
Requires Microsoft .NET 4.5 (this causes the above limitation and is something I can most likely roll back to .NET 3.5 or 4)
The SolidWorks translator currently only supports SolidWorks 2014 and newer (though I could roll this back to around SolidWorks 2010 possibly, I should have the older SolidWorks.Interop files somewhere, which are forward, but not backwards compatible).
The Inventor translator currently only supports Autodesk Inventor 2014 also, for the same reasons. It will be much harder for me to get the older interop files for this.

For both the SolidWorks and Inventor translators, you can try to run them with older versions, but I have not checked all the api calls to see which versions of their respective software they were implemented. So if I used an API call that was implemented in say, 2013, it would require that as a minimum version.

Finally, here are the links

SolidWorks Brick Builder
Inventor Brick Builder
DXF Brick Builder

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?
