    Good generic 3D modeller, but not as suited for quick space modelling.

    Sketchup has useful features for designing houses, furniture and similar objects quickly. It has an intuitive, simplified CAD UX and you can easily add measurements of important parts. Blender is very complex and intended for 3D CGI, not quickly designing objects. I'm sure Blender has plugins for putting measurements in and so on but it has a huge learning curve.

    Although it seems like it has progressed a lot and there are plugins to reduce the gap with sketchup, it is not an alternative unless you already use Blender all the time. Sketchup is like paint for 3D: perhaps not the most powerful, but it does not get in your way. Blender complexity does not solve Sketchup limitations (accuracy, constraints, etc). Freecad would be better for that.

    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.

    Completely different scope. SketchUp is a general modeller with a hard surface / architecture focus while MakeHuman is strictly for creating realistic human models.

    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.
