LeoCAD

LeoCAD is a CAD application that allows you to design virtual models using LEGO® bricks. With an intuitive interface, LeoCAD makes it easy for new users to start creating models without spending too much time learning the application. However, it also offers a rich feature set, allowing experienced users to build models using advanced techniques.

LeoCAD is fully compatible with the LDraw Standard and related tools, meaning you can share and download models from the internet. It also utilizes the extensive LDraw parts library, which contains over 10,000 different parts and receives regular updates. The program is cross-platform, with native versions available for Windows, Linux, and macOS.

This ensures that users are familiar with the interface no matter which operating system they use. LeoCAD is also open-source, meaning anyone can contribute fixes and features, and it will always remain free. Whether creating building instructions, working on large models, or using multiple views simultaneously, LeoCAD provides a powerful and versatile platform for designing with LEGO® bricks
