The last two-three days I stuck to drew the drawing of whole building because at present FreeCAD have not the capability for recording everything in a macro because some code is written in C++ and in Python.
After struggling, today I discussed my problem with sir and he gave me many ideas that how I can overcome this problem.
I also chat on IRC of FreeCAD channel and discuss my problem with Yorik that how to draw the drawing of the whole building through Python console. I was using fuse function of FreeCAD in ‘Part’ workbench and he told me not to use fuse function. He told to use Part MakeCompound tool and which was solved my problem. He also told that compound is much, much faster and corrected than fusing.
In python use
Part.makeCompound( [list of shapes] )
