LeoCAD Easy to Use
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.
LDraw Compatible
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 over 10,000 different parts and continues to receive updates.
Cross Platform, Open Source
Native versions are available for Windows, Linux and macOS to ensure that users are familiar with the program interface.
LeoCAD is open-source, so anyone can contribute with fixes and features, and it is always going to remain free.
