Installation

You can download the latest version of LeoCAD and its Parts Library from the main website at https://www.leocad.org

It's recommended that you install the latest drivers for your video card since LeoCAD uses OpenGL to take advantage of hardware acceleration for rendering.

LeoCAD for Windows

Download the latest LeoCAD-Windows.exe to your computer, double click on the icon to launch the installer and follow the instructions.

LeoCAD for Linux

There are multiple ways to install LeoCAD on Linux.

  • Snap Store
    You can find LeoCAD in your distribution's Snap Store. Alternatively, you can enter sudo snap install leocad to install it using the command line.

  • AppImage
    Download the latest LeoCAD-Linux.AppImage, make the file executable (chmod +x) and run it.

  • Flatpak
    You can also install LeoCAD releases as a Flatpak from Flathub: https://flathub.org/apps/details/org.leocad.LeoCAD
    Note: there might be a delay for new releases to appear there. If you have it already installed, it will be updated.

  • From source
    If you prefer to compile LeoCAD yourself, go to the GitHub releases page at https://github.com/leozide/leocad/releases/latest and download the source archive from there. If you do not already have a Parts Library installed, you will need to download one and follow the installation instructions. More information on how to compile your own executable is available in the Documentation section of https://www.leocad.org

LeoCAD for macOS

Download the latest LeoCAD-macOS.dmg to your computer, double click on the icon to open the archive, copy LeoCAD.app to your Applications folder and then launch it from there.
