How is it possible to get the main bearing of buildings by floor plan?
I want to have a building (by ID) and it's main bearing (e.g. E/90° or W/270°). The idea is to change the polygon-feature class into a line-feature class. Then I can calculate the lengths of each side. I can also calculate the bearing of each side. Buildings with a more complex floor plan I planned to cumulate the side's lengths on the bearing.
The problem is that one building with four parallel sides get four different bearings because of the starting point for the bearing-calculation (see image). Furthermore the calculation doesn’t always start at the same end of a line.
