but still why can't i do measure the network distance when the restrictions are on??
I have one more q. i have 400 points from which i wanna know the distance of some hospitals. but these points are actually centroid of ZIP Codes which i created from the ZIP Code polygons. So, they are in different layers. That's why i have to take each centroid location at a time and do the OD matrix. How can i take the centroid points in one layer so that i will have the network measure in one OD matrix attribute??
