SteamCAD is a drawing tool especially designed to create drawings of steam locomotives. The software is very lightweight, the user interface is minimalistic. As a result, the drawing area is not obscured by controls and can occupy the whole screen. This is what makes SteamCAD different from any other CAD. StreamCAD is focused on productivity, not on the fancy look.

SteamCAD is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!
AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.
Unlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.
Behold! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!
Download the SteamCAD AppImage and make it executable using your file manager or by entering the following commands in a terminal:
Then double-click the AppImage in the file manager to open it.
chmod +x ./*.AppImage
