LeoCAD is a free and open-source 3D CAD program for creating virtual Lego models by using parts from LDraw library. It was developed by Leonardo Zide in 1997.

== History == LeoCAD is developed and released by Leonardo Zide around 1997 under GPLv2 free and open source software license. It is written in C++ and uses Qt as GUI. At first it was a standalone CAD software with its own brick library, but soon it was updated to adopt the LDraw library and file format, an unofficial Lego parts collection that was very popular at the time. As of 2024, LDraw contains over 10.000 pieces and still gets updated with new bricks.
