A 3D modelling program for creating virtual LEGO models

LeoCAD currently has a library of more than 1000 different unique pieces (but they don't represent any particular brand), most of them created by James Jessiman (the author of LDraw).

LeoCAD is a CAD program that allows people to build virtual models using bricks similar to those found in LEGO toys. LeoCAD can be used to create building instructions and animations, making it a very powerful editor.

Each object in a LeoCAD project can have a different position and orientation for each step or frame that it appears. This feature is called keyframing, and works differently if the program is in Instruction or Animation mode.
