In my opinion, you're doing this the time consuming way by running around the game.
Getting your coordinates in the CS is going to be faster.
I also don't think there is a console command for finding axis direction. (although for
exteriors North is always 0, South is 180, etc.)
Open the cell you want, and place a NPC on the floor where you want to spawn when teleporting.
Now at the bottom of the CS you will see six coordinates, looking something like this:
-159, 65, 127 [0, 0, 45]The first three are the position placement in the cell. The three in brackets are the axis coordinates, with the last number being the direction an NPC would be facing on a 360 degree axis.
It's best to exit without saving when you're done, so you don't have references of NPCs being in the cell
