During initialization the error No module named pivy occurred in /home/ruchg/.FreeCAD/Mod/FreeCAD_assembly2/InitGui.py

which is not surprising since FreeCAD is running Python 2.7:

Please note that the Drawing+DrawingDimensioning combo is deprecated in favor of TechDraw.
Although some few things like special symbols are much more difficult to obtain in TechDraw, it is much more advanced in many aspects. You should give it a try.

Sorry about this question, but why not use TechDraw workbench ?
Drawing Dimensioning is more or less obsolete.
