I found that FreeCAD is the best solution. The python bindings lets you design parts in a comprehensive way.
<pre><code>myShape = Part.makeBox(2,2,2)
myShape.translate(Base.Vector(2,0,0))
</code></pre>
From simple geometries you can use boolean operations:
<pre><code>cylinder1 = Part.makeCylinder(3,10,Base.Vector(0,0,0),Base.Vector(1,0,0))
cylinder2 = Part.makeCylinder(3,10,Base.Vector(5,0,-5),Base.Vector(0,0,1))
common = cylinder1.common(cylinder2)
</code></pre>
The only downpoint is the installation with mac os, I could not compile it on snow leaopard (because too much dependencies on unsustained libraries).
But pythonocc has the same problem and what i don't like is the minimal documentation and the synthax which is too much opencascade like and not to much pythonistic.

<a href="https://github.com/dcowden/cadquery" rel="nofollow noreferrer">CADquery</a> is a plug currently for FreeCad that I have used and worked better than scripting OpenScad in Python. The developers are currently moving from FreeCad to Python OCC for Version 2 but I am currently plugging away with V1.

CQParts is a really important part of what makes cadquery useful. It is an analogue of procedure so you design one wheel etc.

PythonOCC is probably the most feature complete. Here are some more:

<a href="https://code.google.com/p/caddd/" rel="nofollow">CADDD</a> - uses PythonOCC, has GUI in Qt.

<a href="http://runten.tripod.com/NURBS/" rel="nofollow">NURBS</a> - Python module for working with NURBS.

<a href="http://diyhpl.us/cgit/lolcad" rel="nofollow">lolcad</a> - looks very good but it was not updated for quite some time.

And of cource, you can try to use Blender, which has build-in Python interpreter and there are plugins for architecture and precision modeling (like <a href="http://wiki.blender.org/index.php/Community%3aScience/Architecture" rel="nofollow">this</a>)

Well, it seems the python bindings for FreeCAD is the best but are there other things out there?
