Yes. As a last resort yes. Although that comes with other problems due to a house drawing attracting mouse clicks to everything else but objects in front.
WANNABE MIDPOINT
Another problem which fooled me totally is that midpoint doesn’t atually give midpoint for objects that has been cut, like in this case a window frame, which had me spend hours making the smaller window frame to fit only on one side before I discovered it. It turned out only later I was significantly off center (see orange and red curves).
Now, this ended up in a mess before I understod what was going on but I attach the win drawing anyway. Do you see the same off-center-wannabe-midpoint? Or am I totally off myself? 
Btw, I’m not an architect, just trying to draw my daughters house prospect according to her “visions”.
