Town Plan / System in play
Sets 1210, 1211, 1212, 1213 and 1236 — the first true model sets!

In 1955, TLG launched the System i leg ("System in play") branding concept, which was the genesis of what we now simply call the Lego "system". System i leg was a line of small model kits, parts packs, accessories and HO-scale vehicles that, together with the existing Lego Mursten gift boxes, all centered around the "town plan"—a soft plastic mat that had a city streetscape laid out on it. So you could say this was also the beginning of the Town theme (although the idea of themes wasn't really introduced until Legoland in the 1970s).

These five small model sets included, for the first time, a selection of parts intended to build specific models, and there were instructions for those models enclosed in the box (as opposed to in the catalog, as with the gift sets of 1954)—another first, although standalone instructions wouldn't become commonplace for about another decade. The models were a collection of small shops or houses, and a garage with a clever automatic door.

These sets went through a few different versions over the years, as slotted bricks were retired and tabbed windows replaced with studded ones, and like all early sets, the exact contents tended to vary quite a bit anyway. When Lego started selling in Germany and beyond, these were sold with 3-digit set numbers (210–213 and 236) to differentiate them from Scandinavian sets that still had the slotted bricks. The 3-digit set numbers became universal in 1958.

Hello, since I allready opened severel thread for the same thing, maybe it would be better toopen a thread to report all of the misisng ering in parts.

Today it's https://www.ldraw.org/parts/official-par...id=2586p4n

A 2-4 ering sould be add in the main model :

So I got this great idea to do a "watch me build this in LDraw" livestream on YouTube or some other platform. Unfortunately it would have to be in the evening my time (Pacific) so that's super late for the US East coast or supper early for Europe. Is there any interest in something like this?

Hi everyone... this is my first post.  I made a custom mini Wall-E I created (with instructions) for my little boy's Wall-E themed birthday party!!  I love working with AutoCAD but never knew there was a Lego version!!!!! LDraw is now my favorite place!

   

I have tried looking trough every minifig accessories in studio and I have also searched sack on rebrickable and bricklink, but I am not able to find it. Does anyone know what this piece is? It looks like it is from lego. It fits in a minifigs hand.

Hey,

I recieved a mail from Willy and transformed it into a new LDPatternCreator version.

Download and install the latest LDPatternCreator release directly from sourceforge.net.
Any previous version should be uninstalled first. Your program configuration will be preserved.

Change log:

New features:

• Included the latest #-#tang primitives (1-16tang.dat, 1-8tang.dat, 1-4tang.dat, 48\1-16tang.dat, 48\1-8tang.dat).
  

• "Add Vertex" was not compatible with the "Create a Spline..." feature.
  
• Version 1.7.2 triggered a false alert on Windows Defender. I had to increase the version number and re-build it.
  

Quote:Bug-Detail:

•     Select "Add Vertex [A]"
  
•     Set a vertex. Watch out for the small coordination windows in the bottom right-hand corner
  
•     Select "Add Primitive [F7]... Create a Spline..."
  
•     Click to add the spline starting point
  
•     Click to set the first direction of the spline
  
•     Click to add the next point
  
•     Click to set the next direction
  
•     You CANNOT click to apply the segment count because the "Vertex-Data" is still there hiding the segment count window underneath.
  

Hello,

I am working on a set of steam train driving wheels that I 3D print and I want to have LDraw parts to share. I know I can go the route of STL->Dat but the files are HUGE (10k+lines) and I would like to optimize a little better. 

So far my thought is to have a slice of the outer ring that is 1LDU thick but has the profile of the wheel then take and spin that 360 degrees. I can then create a center section of spokes and other features from there. The "problem" is that the largest size of steam driver I am looking to produce is 386 segments (123LDU diameter). Is that "too much" I see that there are other primitives that I can use to create some of the faces but I am worried that the resolution is not high enough for something so large. 

I have attached and example of this. 

I am really looking to make sure I am at least headed in the right direction and that I am not doing something needlessly over-complicated. 

I would think that the creation of a file would go something like this

• Create inner connection 
  
• Create rim(s) at sizes needed
  
• Create associated details
  
• Create the "final" wheel(s) which will have reference to the various pieces needed

Guys,

as you might have noticed a new script has been added to the PT links a while ago, listing the "Weekly New Parts":

Beside the new parts it gives you a good overview of the "Oldtimers", parts that are in review hell for ages because of some issues - mostly abandoned by their authors. I started reviewing and fixing some of them a long time ago and would appreciate if you could have a look and get them into an update:

Regarding the Mursten-era door (u8012) and windows (u8019–u8024):

The geometry of these parts is not quite right, and leads to collisions when the tabs are interlocked as intended. I propose this modification, which avoids these collisions, and also those that arise by placing the tab behind a neighboring brick (as seen here). But the real geometry may be a slightly thicker tab that fills the slot better, with the part itself being slightly less than a brick-width in Z (so maybe 18 LDU or so), relying on the part's flexibility to fit behind or in front of a neighboring brick.

This revision also subfiles the tab, for brevity's sake. I use u8021 as an example, but all seven parts would be affected.
