LDU stands for LDraw Unit - the basic unit of measurement in LDraw, the open standard for LEGO CAD programs, and map to the "Fine" grid setting in applications such as MLCad. Common measurements include: 1 brick width/depth = 20 LDU 1 brick height = 24 LDU 1 plate height = 8 LDU 1 stud diameter = 12 LDU 1 stud height = 4 LDU A ...

(Note: my HDD crashed recently and until I get that fixed I can't really make LDraw images. I did create one for this beforehand, but it's on the same HDD.) As jfyelle said the solution consists of using one LEGO element which has an odd ldu dimension somewhere. There is such an element, which isn't even new or particularly rare, that is, the Fence 1 x 4 x ...

There is another piece with an odd LDU dimension: the 1x1 bracket is 3 LDU thick. Paired with an Erling brick, which has a 4 LDU offset built in, it's a very compact way to create a 1-LDU offset, like psiaki has done here: Then it's just a matter of translating the offset into a gap between bricks using standard bracket pieces like I have done here:

This in not a LDView problem, but a conversion issue between LDD and LDraw. Only parts present in both libraries will be displayed. Moreover, the file (ldraw.xml) that defines the correspondance between parts of both systems must be up to date. Latest version of this mapping file is available here.

The models included in AIOI as mentionned by HaydenStudios is also available as separate download There is also a huge collection of LDraw models of official sets available on Eurobricks forum

Both, often in the same file. If you take a look at the .ldr file format specification you can see that each file is made up of an number of different types of "line", one of which is a Subfile Reference where you can specify the colour, position, rotation and scale of the model. Other lines can then be added to describe Lines, Triangles, Quadrilaterals ...

LDUs are synthetic units for LDraw, a lego design software. (I am personally convinced that the correct answer to your question is that there is no way to create a 1 LDU gap and that we are very fortunate to have the Erling brick to create a 2LDU gap.) If you look at the 2 links provided, you'll see that both the Erling and the standard lego brick ...

This answer will by definition have a lot of links, but here we go. Since you're looking for instructions there are a few sites that you should consider visiting. The first is Cubiculus, which specializes in creating LDraw versions of custom and official instructions. The creator of the site adds plenty of his own (basic) instructions. The second is ...

I don't think you "import the document into LDraw" since I don't think there is an LDraw program; it's a library of all parts. CAD programs manipulate those parts. I tried various CAD programs over the years and recently found that LDCad (which you say you recently installed) works for me. So what you want to do is to import your Rebrickable parts list ...

If you have a LEGO Digital Designer file (.lxf) and want to convert that to an LDraw compatible format so that LDraw-based tools such as Bricksmith can read it, your best bet is to use LDD's Export functionality to save your file as a .ldr file. The full details on this procedure are located here. This post covers both LDraw to LDD as well as LDD to LDraw ...

You have no need to use these unofficial parts, all EV3 parts (except for the stickers) are now LDraw official parts, and should already be in your library if it is up to date (otherwise, download and install complete.zip from here). The problem you most probably have is that the file LDraw.xml that directs conversion between LDD and LDraw doesn't support ...

Perhaps this Eurobricks thread is helpful: https://www.eurobricks.com/forum/index.php?/forums/topic/108739-new-parts-for-lgeo-library/ It seems that the lgeo library itself is no longer maintained but this person maintains his own version. The download links are on the first page...

As stated in your "various places" link, the LDraw.org web site maintains an All-In-One-Installer (AIOI) which contains and installs LGEO and is updated in January every year so I assume they use the latest version of LGEO. BTW, I found an LGEO quirk when launching POV-Ray from within LPub3D which I use for generating building instructions. I kept the ...

Starting from LDD files and LXF, a good software is Blueprint from msx80 https://www.eurobricks.com/forum/index.php?/forums/topic/108346-software-blueprint-a-building-instruction-generator-for-ldd/ With this, you can organise how you want the pieces to get assembled (by default the auto-generated steps are not always optimal), then export a PDF, I think it'...

The LXF file contains the complete model as created with Lego Digital Designer (the Lego CAD tool from The Lego Company). The model usually doesn't require to have building steps as they are (always) automatically generated from the model. For normal, non-Technic models, Lego Digital Designer (LDD) is able to create automated building instrutions. My ...

.3DS is a 3D image file format, a rendering of what you designed in LeoCAD. All information necessary to recreate your build (i.e. what bricks to use) will be stripped from it. I suppose that theoretically this information can be recreated for small builds, but for medium-sized to large builds, this will simply be infeasible. Hence I think it quite unlikely ...

I have now figured out that you can include submodels the same way as normal parts. In LeoCAD, go to the parts panel where you can select a category ("All Parts", "Parts in Use", ...), scroll to the very bottom and select "Models". Then you can select your submodels and incorporate them. (For some reason, my submodels still don't show properly in LPub3D, ...

It looks like I might not be doing anything wrong after all. If I switch the preferred renderer from native to LDView under Preferences everything looks fine. Maybe I should mention that I am using LPub3D 2.3.6 under Linux. At least the Linux version seems to be rather buggy. It regularly crashes with a segmentation fault when you try to edit the ...

Cannot comment on LeoCAD as I've never used that, but LDCad is far superior over MLCad and it works well on Linux natively. LDCad uses same part library format as MLCad - LDraw. You cand find LDRaw file documentation here. It is not clear from your question if you wish to create your own parts or just add the ones not currently available in official LDRaw ...

This wiki page describes how to get all the LGEO parts. https://wiki.ldraw.org/wiki/LGEO

This is now available on Github. I was able to find a working download of just the original LGEO library on Eurobricks thanks to some help from the other answerers. I trimmed that down a bit, as that download required integrating some other files in order to work properly. This repo should now work perfectly on its own, but it only includes parts up through ...

You can use LDD (Lego Digital Designer) the official LXF viewer by Lego. This allows you to create building instructions to view or export to html. You can also use this software to build models, and i find it much better than other softwares since it is simple, with easy UI.

LDD will produce printable instructions on its own. You can print these into PDF files. Do you not like the LDD-produced instructions?

Another option is the LEGO Club Magazine - available online and through the post in some countries too - they have three editions: Green Brick - Junior builders, probably what you're looking for at this stage Yellow Brick - Mostly Friends/Elves focused, but with some City/other Red Brick - Mostly City/Chima/Bionicle, but with some others as well All of ...
