About this software:
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.
Version 0.83.1.9306 is a freeware program which does not have restrictions and it's free so it doesn't cost anything.
Virus and Malware Tests: The program has been tested with several antivirus applications and has tested clean of viruses, malware or trojans.
