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.

sudo apt update && sudo apt upgrade

2. Download QCAD 2D for Linux

As we have discussed in the introduction to this tutorial, QCAD is not available to install using the Ubuntu 22.04 system repository. Therefore, we have to manually download it from the official website of this open source CAD application. Here is the link to visit it.

Go to the Linux section and download the professional version of TRAIL for your Ubuntu 22.04 Linux. Don’t worry, if you want the community version, then we will get it in the next steps.

chmod +x qcad-*-trial-linux-x86_64.run

4. Install QCAD for Ubuntu 22.04

Ditch the professional edition and create open source CAD

By default we will have the trial version in our Ubuntu 22.04 of QCAD. Now, if you don’t need the professional license, instead of buying it, convert your Trail Professional edition of QCAD to a community edition. For that, in your command terminal run the given commands:

Switch to QCAD installation directory under /opt

cd /home/$USER/opt/qcad-*-trial-linux-x86_64/

Now enter the accessories directory:

cd plugins

Remove PRO edition plugins:

sudo rm libqcaddwg.so libqcadpdf.so libqcadpolygon.so libqcadproj.so libqcadproscripts.so libqcadspatialindexpro.so libqcadtriangulation.so

Now, open the app again and this time you will have the community edition:
