LeoCAD

LeoCAD is a computer‑aided design application that lets users build virtual models using LEGO bricks. It provides a graphical interface where individual pieces can be placed, rotated, and connected to assemble detailed constructions that can be viewed from any angle. The software supports standard LEGO part libraries, enabling accurate representation of real‑world elements in a digital environment.

The tool is aimed at hobbyists, educators, and designers who want to experiment with LEGO creations without physical bricks, or who need to plan complex builds before assembling them. By offering a visual workspace for arranging bricks, it helps users visualize structures, test stability, and explore alternative configurations quickly.

LeoCAD runs on macOS as a stable release, delivering a consistent experience for users on that platform. Its focus on LEGO‑specific parts and straightforward modeling workflow distinguishes it from general‑purpose CAD programs.
