Modern computers and laptops are mostly 64-bit. Just in case, you may press Ctrl+Alt+T on keyboard to open terminal, and run command uname -m to tell.

For choice, you may go directly to the file host server and select download the latest “SweetHome3D-x.x-linux-x64.tgz” package.

2. After downloaded the .tgz tarball, open “Files” and navigate to the Downloads folder.

Then extract the tarball, and move the “SweetHome3D-7.5” sub-folder into a custom user folder (in my case I created “MyApps” folder in Home) for long time use.

Finally, navigate to that app source folder. Right-click on the “SweetHome3D” file and click “Run as a Program” to launch the home design software.

If the software launches without any error, you may continue next step to create app shortcut for it, so you can search for & launch it from either start menu or Gnome Overview depends on your desktop.

3. To create app shortcut for Sweet Home 3D, first search for and launch “Text Editor”.

When text editor opens, create an empty file if need, then paste the lines below into it:

[Desktop Entry]
Version=1.0
Name=Sweet Home 3D
GenericName=Interior 2D design application with 3D preview
Comment=Interior design Java application for quickly choosing and placing furniture on a house 2D plan drawn by the end-user with a 3D preview
Exec=/home/ji/MyApps/SweetHome3D-7.5/SweetHome3D
Icon=/home/ji/MyApps/SweetHome3D-7.5/SweetHome3DIcon.png
StartupNotify=true
StartupWMClass=com-eteks-sweethome3d-SweetHome3D
Terminal=false
Type=Application
Categories=Graphics;2DGraphics;3DGraphics; Keywords=interior;design;2D;3D;home;house;furniture;java;

NOTE: You need to replace the text in BOLD in lines of “Exec” and “Icon”, according to where you moved the Sweet Home 3D app folder to.
Just navigate to that folder, press Ctrl+L then copy the PATH, finally use it to replace the bold text above.

When done editing the file, press Ctrl+S or Ctrl+Shift+S to open the “Save File” dialog. Then,

  • set whatever file-name with .desktop extension.
  • navigate to Home -> .local (press Ctrl+H to show/hide) -> share -> applications for where to save the file to.
  • finally, click “Save” button.

If everything’s done correctly, you should be able to search for & launch Sweet Home 3D a few moments later, from either start menu or GNOME overview depends on your desktop environment.
