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.

They adopt new official standards by voting on them, and publish documentation on LDraw.org following such a decision.

The LEGO Universe Team has shared another batch of part shapes with the community, with the purpose to make them fit for the LDraw Parts Tracker. This time things are a bit different. The package we’ve got contains also shapes which are already official parts or at the PT for certification. You can help out sorting by comparing the part numbers with the official parts, the PT and the shapes we already have.
