I work in a building, which is divided into 3 parts; one on the left, the middle section and the one on the right.

The front door in in the center of the building, facing north. The building is irregular shape; there are missing section; N, S and some NE.

All 3 part have different roof. My question is how do I calculate flying stars for this building? Do I calculate 1 chart for the whole building or

I plan different chart for the secton on the right and and another 1 for the left part? The section in the miidle where the front door is located is not very big; it is just the front door.

What do you think?
