How to install Qcad 2D free on Ubuntu 22.04 LTS

Get started creating 2D technical drawings by installing open source QCAD on Ubuntu 22.04 LTS Jammy Jelly Fish using the command terminal.

If you are looking for a free and open source CAD application on Linux to draw various 2D interior drawings, machine parts, structural construction plans, diagrams and more, try QCAD. It is available in community and professional editions for two-dimensional (2D) computer-aided drafting (CAD).

Apart from Linux, we can also use it on Windows and macOS. Offers Blocks (grouping); 35 CAD fonts; DXF and DWG input and output (professional version only); More than 40 construction and 20 modification tools; Measuring tools; Command line tools (dwg2pdf, dwg2svg, dwg2bmp, etc.) and more…

As of Ubuntu 12.04, QCAD is no longer included in the sources. Instead, the QCAD package installs the LibreCAD program. LibreCAD uses the same code base as QCAD, but the graphical user interface is adapted to Qt4.

Its source code is available on GitHub.
