Floor span direction line extract

Hi All,

How would one extract floor span direction in a form of a line? I want to draw joist positions as polylines but I need to somehow extract the direction in which my lines are supposed to be running.

Thannk you for your help in advance!

Regards,

Jonas Blazinskas

Any idea why I am getting 6 ouputs when I only have 3 floors? As well as I only have 1 floor spanning in different direction out of 3 so not sure why i have 3 x a value of 0 or 1.57?

bump still not resolved
