As in 2025 (and presumably before also) brlcad and qcad are NO longer available for install in terminal. In both cases I got the notification; ‘the packages CANNOT be found’. Building from source (for the die hards which I am not in linux) is possible. This means end of the road in my case. So adjust your website information.
Flatpak: QCAD offers development snapshot Flatpak builds for Linux (Qt6) (qcad.io). You can check your platform (x86_64 or ARM64) and install using a command like:
flatpak install org.qcad.SNAPSHOT
(Exact name may vary — you can search on Flathub or install from a .flatpak file downloaded from their forum.)
AppImage: The QCAD Community Edition sometimes has AppImage builds available. These have been listed in AppImage collections (UbuntuBuzz) alongside Blender, LibreCAD, etc. (ubuntubuzz.com). You’d need to check the official site or GitHub for the latest .AppImage.

BRL‑CAD
Flatpak: A Flatpak build for BRL‑CAD is being worked on in Flathub (pull request opened July 2023) but is not yet officially released (github.com).
https://github.com/BRL-CAD/brlcad/issues/88
AppImage: Some users have requested it, but no official AppImage exists yet .
https://sourceforge.net/p/brlcad/support-requests/128/
Binary: The official website and GitHub releases sometimes provide precompiled binaries for macOS, Windows, and Linux — but only if the developers include them for that release (github.com). The latest version (7.40.2, Oct 1 2024) may have Linux binaries available.
https://github.com/BRL-CAD/brlcad
For QCAD
Search for it on Flathub:
flatpak search qcad
If a snapshot package is found, install it:
flatpak install com.ribbonsoft.qcad.SNAPSHOT
If not, look for a QCAD Community AppImage on GitHub or appimage.org, make it executable, and run it:
chmod a+x QCAD-*.AppImage
./QCAD-*.AppImage
For BRL‑CAD
Check the GitHub releases (e.g., v7.40.2) for Linux binaries.
If available, download and install:
tar -xzf brlcad-VERSION-linux.tar.gz
cd brlcad-VERSION
./install-script # or run binaries directly
If no binary exists, building from source is currently the only option.
