This one is slightly challenging ! .. I have some building polygons. I have converted them to polylines. Wherever the polygons shared a boundary there i have two polylines now with different height attribute. They are actually nothing but adjacent walls of a building which differ in height.
I want to calculate the difference between these two.
So basically, I want to identify all places which have duplicate polylines and then I should be able to find out the difference in their height attribute field.
Any ideas would be much appreciated..
Thanks and Regards,
