Best Free CAD Program for Linux

Sweet Home 3DSweet Home 3D is sure to tickle every bone in your body. You can model your dream home, along with all of its cherished appointments, and then watch it come to life. You can start simple with just the bare walls or import an image of your intended floor plan to serve as a basis for the design-to-be.

The user interface is as intuitive as it gets; drag and drop furnishings from the built-in catalog onto your floor plan. Clear graphic handles then make it easy to edit the items. Once you've finished your home design and tweaked every niche and corner to your liking, the fun has only just begun. (Review)


BlenderBlender , a complete software package for 3D modeling, texturing, rendering, animation and physics. It has a complex but merciful user interface, and the entire repertoire of its capabilities are made available through a scripting language, so the creation of 3D games beckons.

The software can import from and export to more than 20 different file formats. There is a large and growing community of Blender users who've already contributed numerous add-on scripts that can make your going easier. If it can be imagined then it can be realized, with Blender freeware. (Review)

Best Free Image Editor for Linux

Luminance HDRGIMP , currently the only freeware package I am aware of that can be called an advanced image editor.

If you are inexperienced at using image editing programs GIMP will likely be too overwhelming to start learning on as it has a steeper learning curve but it is feature rich. It has lots of advanced features and can do almost everything the Photoshop can do.

Its multi-windowed interface makes it a little unusual if you're used to a windows program. (Review)

Best Free Paint Program for Linux

MyPaintMyPaint , designed for pressure sensitive graphics tablets, MyPaint allows you to use a large collection of brushes including charcoal and ink to emulate real media, with color changers and opacity controls, unlimited canvas and basic layer support.

You can also download and import more brush packages for use with the application.

Phototonic , an image viewer and organizer to load thumbnails and browse images on a folder tree. Some key features include image navigation, file management, slideshow, transformation, adjustment, display image info and metadata, rotate images based on the Exif orientation tag, find and manage duplicate images, etc.

No executable package is readily available but general instructions to compile the program code and create the executable are given on the developer's homepage.


Best Free QR Code Generator and Decoder for Linux

QtQRQtQR , a graphical frond-end for python-qrtools allows you to easily create and decode QR codes, supporting URL and other data type, configurable pixel and margin sizes, error correction, and save QR Codes in png format.
