    If you are looking for something related to home design, SweetHome3D is an excellent solution. But it is not a general purpose cad suite.

    Sketchup is far more generic and can be used for creating 3D printing models. Sweet Home 3D is a targeted application designed for laying out house designs.

    Sketchup is for quick drawing, to think in 3D. Not for blueprints or super accurate things. Freecad can resolve constraints but is anything but intuitive of fast. They can't be compared.

    FreeCAD is a rich program for mechanical components or structures. There is more of a learning curve than Sketchup but can create professional drawings, analysis, simulation, assemblies, and more.

    The manner in which you draw a shape, enter dimensions, and push/pull a flat plane shape are the most similar to the SketchUp workflow of any 3D/CAD program I have used.
