Hi, many latest sets contains the techic "standard" bush as part 6590, but it doesn't appear on the ldraw library. The library contains part 3713 that looks identical to me. Maybe they could be aliased somehow ?

Peeron says to use 3713 for 6590.

Hello!

There is a technic part 87408 and 87408s01 I copy to the parts folder and start Mlcad, make a scan parts, is says "new parts found! Write new Parts.lst file?" I click yes and if I try to select the part it says "File s\87408s01.dat not found! Continue loading?"
I click yes but the parts isn't there.
Please help me.

Hi guys,
I'm new to LDraw and recently I created my own parts in LDraw.
I would like to reuse the small part created in another larger part but I cannot use the small part as a sub-part, should I upload the sub-part to library or just put it in the p file(but seems like it cannot be recognized if I only put the sub-part in p file)?

Do you know what I mean? What should I do, any helps please?

We've shifted our theme colors to better match the main LDraw.org website (and I thought the grey was a bit drab). Any feedback would be appreciated.

I am trying to write a renderer and so trying to understand the document http://www.ldraw.org/article/415.html.
My first question is does a reverse matrix (determinant < 0) perform a mirroring on the part as I have seen in some places or just changes the winding as the document suggests. I wish the pseudocode at the bottom of the document also included the negative determinant part of the drawing process.

Also regarding rendering. If I open the subpart box5.dat in ldview the backfacing polygons are not rendered. But If I create a file sample.dat and in it I put the line "1 16 0 0 0 1 0 0 0 1 0 0 0 1 box5.dat" and open sample.dat in ldview then the backfacing polygons are rendered. From reading the above document I do not understand why that is the case.

Thank you for any help.

Hi all,

For those that don't know me, I am the creator of Rebrickable. I make heavy use of your LDraw library of parts for the images on my site which are rendered via L3P/POV-Ray.

I thought you might be interested to know that I've now made all the images available for easy download from the site http://rebrickable.com/downloads

Hello, i'd like to draw a model that has x1681 non-technic threads in it.
I've understood that i have to use LSynth to design it, but from the tutorial it doesn't seem it handle that particular thread type. Can anyone confirm this before i adventure into learning to use it?

Thanks

This year there seems to be many "old" patterns printed on the new head, 3626c, and perhaps we need to decide how to treat them.
Must there be both a 3626b and a 3626c version of every re-released pattern?

Should all b-heads be renamed to "...with Blocked Stud"?
Should all c-heads be named "...with Hollow Stud"?
I don't think that's necessary.
The "c" in the partnumber, 3626cpXX.dat, tells me that it is a new head, with hollow stud.

Howard Lande has made a number of new heads, both as b- and c-heads.
3626bpb122, 3263bpb322, 3626bpb366, 3626bpb411, 3626bpb471, 3626bpb633, 3626bpb719
3626cpb122, 3263cpb322, 3626cpb366, 3626cpb411, 3626cpb471, 3626cpb633, 3626cpb719
(btw, they all need renumbering too)

Is that really necessary?

Is it only me or...? At first I thought LDView was making an April joke, which was almost a bit funny too. The thing is, if you have more than one copy of a submodel, LDView will render all of them a bit smaller. And - the more you have, the smaller all of them get!

I tried this with the 64bit versions of 4.2 Beta 1 (downloaded from SF) and 4.1.1.25 that I had previously compiled for 64bit. The 32bit version of 4.1.1.25 does not show this behaviour.

Steps to reproduce - make a model with one simple submodel (a 1x1 brick is enough), copy the submodel 4 times or so into the main model, and see what happens. Then double the amount of the submodels and press F5 in LDView.
Or download the model attached to this message.

Following the tradition of TLG sharing information regarding the brick shapes we've got a new batch of what we use to call L(EGO)Draw parts.

http://news.lugnet.com/cad/?n=14755

This time they were not provided through the LEGO Universe channel (as you can surely imagine ;-) but directly by the LDD team itself. Also the formula has slightly changed: To shorten the time between the release of a part and when it has been finally certified through the LDraw Parts Tracker for the first time TLG provided data of prototypes. Those will be available in sets only in 2014. This leaves us with plenty of time to make them fit for an official LDraw parts update.

Though we will get only parts which have already been copyrighted we are still talking about highly sensible data. Only part authors and reviewers who have signed a NDA - non-disclosure agreement will get access to the L(EGO)Draw prototypes. Chris has set up a some sort of parallel PT and you will need a second account/password. The parts will then be held in queue until they actually hit the market. If you're interested to join the team just leave a short reply to this message.

However we've got permission to share a small sample with the community to get you an idea what's all about:



As usual I have uploaded the corresponding .dat files to my webspace. Just add the part number to the follwing path with one example provided:
