CAD application for creating virtual LEGO models
LeoCAD is fully compatible with the LDraw Standard and related tools, and it reads and writes LDR and MPD files so that you can share and download models from the Internet.
It also uses the LDraw parts library, which has almost 10,000 different parts and continues to receive updates.
LeoCAD has an intuitive interface that is designed to allow new users to start creating new models without having to spend too much time learning the application.
At the same time, it has a rich feature set that enables experienced users to build models by using techniques that are more advanced.
Super awesome! Sort of like LDD
