Hello,
I'm back with more questions! 
From your pictures of a warehouse drawing, how do you determine the side of the bin that has an opening? Does the angle determine the opening side?
Also, we discovered that our warehouse is 16 degrees off from facing North. So, if we were to set up our warehouse drawing would the whole warehouse drawing be off by 16 degrees based on the navigational N,S,E,W?
For example, in your drawing I will assume that this warehouse layout is facing North at 0 degrees so it is perfectly aligned with North on a compass. The picture below shows this.
Since our warehouse is off by 16 degrees would the Y axis be determined by the 16 degree difference? Please see picture below.
