I have two layers, lines and polygons. Lines are basically the boundaries of the polygons. Is there any way that when I change or reshape the lines the polygons get updated automatically? I normally change the lines first and since they have to match the associated polygons, I convert them back to polygons again. This way, I need to update the attributes of all the polygons or I have to reshape the polygons according to the change I did to the line layer. When I use topology check I am able to catch the issues and correct them using the correcting topology options. Nevertheless, I was wondering if there is a more efficient way/ approach to do it.

    What version and license level of ArcGIS for Desktop are you using? In any event I think you should use the term "shared geometry editing" to look for info about this and you will need to use either map or geodatabase topology. – PolyGeo Mar 12 '14 at 5:36

  • Yes, I should have used the term "shared geometry editing" for more clarification. – Arash Mar 12 '14 at 22:33

There are many topology tools in ArcGIS but you need at least Standard or advanced licence. As you can use "feature to polygon" and topology check, I assume you do have it.

Therefore you can add the "topology toolbar" (for 9.3 or for 10). There is a tool called topology edit tool that will do what you want.

    Map Topology should also be an option for anyone with a Basic license that does not have access to Geodatabase Topology. – PolyGeo Mar 12 '14 at 8:18
