Thank you, that's hugely helpful. I'm actually struggling to get the exterior dimensions because I have furniture or appliances in every corner of every room and I'm doing everything one-handed with one small tape measure.
I have the INTERIOR dimensions of the walls, doors, etc, and figured I could just estimate the exteriors, but presumably due to human error everything is ending up just slightly off (ie, "well, I know this wall is 83cm, but it doesn't line up with this other wall unless I say it's 80.25cm") when I do it this way.
This is the layout of the apartment:
Mine is mirrored, so I have an image of just the floor plan (rather than that 3D Rendering) flipped horizontally. I assume, then, that I would put the "origin" in the corner of the "living room" area?
I guess I will need an extra set of hands to help me get an accurate measurement of the exterior walls and then fill everything in from there, based on the guide you linked - is that better than doing it my way, of taking all the "interior" measurements and then extrapolating the exterior dimensions, or does it not really matter?
Thanks again!
