Hi,
based on all the help and advise I have been given here I would like to promote this forum and LDraw, etc on my website. How do we go about organising all of that? What are the requirements from your side?

Like mentioned in some of the other threads, the current official library suffers from a number of defects which can be corrected automatically but can be somewhat of a pain to new software trying to use the library.

It also has been suggested many times most of these errors can be fixed using an automated process.

So I did a quick hack in the LDCad 1.4 code to make it possible to save corrected .dat files back to disk, this resulted in about 116 corrected .dat files.

Only downside I noticed is the loss of some indenting (only for the corrected lines, as LDCad preserves unmodified line content).

I also noticed some minor mixed dos/unix line endings which are indirectly auto corrected for any file that needed rewriting.

This test includes only 'hour glass quad' corrections, but with some additional tweaks I can also auto correct:

case mismatches
non flat triangles
quad with duplicate point (degrade to triangle)
all zero row or col ref matrix
type 5 line with missing or duplicate control points (degrade to normal line)


Should I continue my tweaks, and compile a patch containing all changed files so someone else can double check and merge them into the part tracker?

If so which corrections are actually wanted, and or which additional correction would be needed/wanted.

ps: this topic might be better off in the part authoring forum, not really sure though, admins feel free to move it.

Hi

I have been using Big Ben Bricks Wheels parts in MLCAD for some time now.
When I entered my model into LDView I noticed it complained about a missing part - ring8.dat.
I Can't seem to find it anywhere.
Does anyone know what to do about this?

What ever happened with the "LCD - LDraw Connection Database"?? As seen here.


Seems like this would have been a good thing.

Hi all,

I'm desperately try to find good picture on the net for 2552px2



I've posted a thread in Eurobricks forum, will see the results.

However, is there someone here that own the part, or that know someone who own the part, that can provide my good picture of the 5 surfaces (front, back, right, left and top)?

This is the only part I'm missing to complete the Blacktron II series.

Thanks in advance.

Hi all.

Working on coding some Java libraries to handle LDraw libraries I hit some parts with errors. Following a brief list with errors/typos I found:

* 3842a.dat uses BFC CERTIFY INVERTNEXT
* 3842b.dat uses BFC CERTIFY INVERTNEXT
* s\3068s101.dat uses color 391 (unknown)
* 973psk.dat uses color 391 (unknown)
* 4150p02.dat uses color 354 (unknown)
* 973p7b.dat uses color 354 (unknown)
* s\2528s01.dat at line 385 there is a triangle with 4 vertices
* s\6582a.dat all quads are "bow-tied"
* s\6582b.dat all quads are "bow-tied"
* s\6580a.dat all quads are "bow-tied"
* s\6581a.dat all quads are "bow-tied"
* s\6594a-c.dat all quads are "bow-tied"
* s\6595a-d.dat all quads are "bow-tied"
* 2907.dat some quads are "bow-tied"
* s\6579a.dat all quads are "bow-tied"

Following Darats idea exposed here

Quote:I wasn't able to use chrd primitives cause there's no 1-16chrd.
So it doesn't look really nice with primitives substitution.

Hello.
I use the LDD for two weeks now and use the LDView to convert the lego models in a format for 3d programs.

Sadly the .ldr (lego draw) file format doesn't save some blocks and flexible things.

Is there a possiblity to get all blocks and flexible stuff into LDview or a other program where I convert it into a 3d format ?

Is it possible to get the .lxf file in a 3d program or can I convert the .lxf file straight to a 3d format ?

In the LDD, is there a flexible grease band ?

Here is a example how I want to apply the grease band:



Also sometimes if I've rotated a view blocks in the LDD, some parts in LDview are rotated/placed weird.

Here is a picture of it:



I hope some people could answer my questions

I feel guilty for requesting such a rare, complicated, and useless part, but I need it! This is the "Technic Engine Tuneable, Block with Trapezoidal Air Scoop" used in a couple of Racers models.

With all the recent commotion I'm thinking it might be useful to introduce a second 'official' LDraw library.

It would be identical parts wise as the master one, but all parts will be formatted in a single .dat using universal winding etc. We could also add normals to those single files without polluting the master LDraw library.

I would basically be a collection of pre calculated cache files. This library could even be made available in e.g. .obj format.

Anyone think this is worth a second look / go ?
