We have a Street FC with multiple subtypes for the road classifications, one of which is a cul-de-sac. We are trying to build a topology to identify dangles, excluding the cul-de-sac (those are obviously going to be dangles).
The problem that we're having is that the rules that we have come up with either show all dangles (and we'll have to make an exception for every cul-de-sac) or if we make a dangle rule for every subtype *except* cul-de-sac then we have dangles where the connecting line segment touches the cul-de-sac segment.
Currently I'm working on this in a local File GDB, the end product will be in an Enterprise GDB environment. We're using ArcGIS10.
thanks for any help.
