What is LDraw?

LDraw™ is an open standard for LEGO CAD programs that allow the user to create virtual LEGO models and scenes. You can use it to document models you have physically built, create building instructions just like LEGO, render 3D photo realistic images of your virtual models and even make animations. The possibilities are endless. Unlike real LEGO bricks where you are limited by the number of parts and colors, in LDraw nothing is impossible.


A request from the LDraw.org Team
LDraw is and always will be offered free of charge. However, bandwidth is not cheap and LDraw.org accounts for 1/3 of the traffic that our generous host, Peeron.com, sees monthly. If you download, use, and/or enjoy LDraw, please consider a small donation.

Administration Announcement

L(EGO)Draw parts
Members of the Steering Committee (SteerCo) have been in contact with LEGO to look at ways of working together to ease the conversion between the LEGO Digital Designer and the LDraw System Of Tools. This relationship has led the LDraw Steering Committee to the Lego Universe project in regards to it's building tools and such. So to help the process along, The Lego Universe team has started to share information regarding the brick shapes to further the relationship.

As a first bunch we've got data of 80 parts and got permission to share them with the community, with the purpose to make them fit for the LDraw Parts Tracker. We are therefore looking for parts authors who are willing to clean up the rough data, do additional primitive substitution, care for the new header specs, stud orientation, BFC ...

Title Banner
In September 1975, during the Saturday qualifying session of the Italian GP, Niki Lauda set the pole position with his Ferrari 312T in front of team-mate Regazzoni. I was very excited when my father told me that the Monza circuit was not so far from home. I insisted until he drove me there!
When we arrived at the circuit the crowd was already gone. I started screaming at the fences of the pit lane pretending to take a look at the race cars. Luckily enough a Ferrari engineer came by and took my hand to visit the garage: it was my first and closest contact with a real Formula 1 car. A car that was going to win the World Championship the very next day.

Though my passion for race cars nowadays is quite moderate, I soon tried to build Formula 1 car once I came out of my dark age: first modifying some original LEGO Technic models, then focusing on the details like a modeller trying to work out new and original creations.
My building approach has changed a lot compared to the one I used in my childhood: the usual shortage of time and space forces me to study and design the entire model before I start building, drastically reducing any improvisation. I was lucky when I discovered some dedicated 3D CAD software including comprehensive parts libraries and other useful design tools for renderings and building instructions. Before that, I was studying different building solutions using MS Excel!

It has passed more than a year since the last election of the LDraw.org Standards Committee (LSC) were held – also because the SteerCo has missed the actual deadlines. Nominations are now open at LUGNET. All nominations must be received and recorded by November 14. Elections will be held from November 17 ‘til November 30.

The LDraw.org Standards Committee (LSC) is responsible for maintaining semi-regular internal discussions on pending file format issues, the overall progress of the LDraw file format and new or proposed developments made by different LDraw-based software authors. They adopt new official standards by voting on them, and publish documentation on LDraw.org following such a decision. The LSC has documented and will document past, current and future LDraw File Formats.
