I am trying to use Street Centerlines polyline segments as the geometry to convert a polygon feature class into a polyline feature class, while also transferring over an single attribute field (named "PROJECTID", type Double).
Unfortunately, even when multiple line segments exist "Completely Within" a given polygon, they still will not Merge (I even cleared out the Field Map section).
I am also not sure what tool to use to transfer the attribute value for my "PROJECTID" field of the old polygon feature into the field for the new polyline feature.
Thoughts?
