Hello Linux Geeksters. As you may know, GCAD3D is a 3D CAD-CAM app capable of interpreting geometry and NC-command in 3D, with an integrated NC-processor and a programming interface for user programs. The latest version available is GCAD3D 2.20, which has been recently released. For more information, see the official changelog.

In this article I will show you how to install GCAD3D 2.20 on Ubuntu, Linux Mint, Debian, Elementary OS, Pinguy and their derivative systems.
There is no repository available, but we can easily download the deb packages from the official site and install them via command-line (I prefer gdebi over dpkg due to the fact that it also handles dependencies). Follow the instructions for your system’s architecture exactly, in order to get a successful installation.
