I am attempting to use the Update (Analysis) tool to update a right of way (ROW) polygon feature class with a roads polygon feature class. The ROW feature class completely contains the roads feature class and I want to 'etch' the roads into it so I have one feature class with different attributes in one field for the roads area vs. non-road area.
The feature classes have identical fields; for my field of interest, I've given different values to the features in the roads vs. ROW classes.
On my computer, this works as expected - the roads are 'etched' into the ROW with the appropriate attributes so I can distinguish roads from non-roads.
However, on my colleague's computer, the update does not 'etch' the roads in...instead, where the roads are, the update creates two polygons with identical geometry - one with the road attribute and one with the non-road attribute.
I haven't been able to find anyone else with this problem by googling. Has anyone else encountered this? Any idea of potential causes?
