Python-scripted Dimensions

[outpaters]

How can I add dimensions to my Part objects in a Python script?

I've tried:
import Draft
Draft.makeDimension(FreeCAD.Vector(0, 0, 0), FreeCAD.Vector(100, 0, 0))
but it returns
Exception: 'module' object has no attribute 'getDocument'

You code snippet works for me. Whjich version of FreeCAD are you using? Maybe check if you can install a later version.
