I have a model in ArcGIS 10.3.1 which splits a large (> 1,000) polygons by a road network (as polylines). Currently, I am using Xtools' Split Polygons, but this would require an end-user to have a copy of XTools which I need to not be a requirement. I have found this tool, but, when I have tried to use it, it takes a very long time to run (much longer than the XTools equivalent). Does anyone know of any other tools which do the same thing, but are not locked behind non-ArcGIS purchasing licenses and are ideally only using ArcGIS geoprocessing tools?

  • @Midavalo, first link has Dalton's answer as best which I've already referenced above as the tool that takes too long. Second link has ET Wizards as the best answer which, without a license, has a max feature count of 300. – jwx Jan 25 '17 at 16:39
  • have you looked at the suggestion on how to possibly speed up Dalton's tool? – Midavalo Jan 25 '17 at 17:58

    Please edit your question to include any extra info rather than as comments. Please also include how long it runs using XTools for comparison. – Midavalo Jan 25 '17 at 19:26

Have you tried "Feature to Polygon", advanced license required? This tool will Cut Polygons with a Polyline FC. If you don't want the Road Network creating new polygons, first Clip the Road Network by Polygons so you are only dividing or cutting the existing Polygons.

  • Funny, I was just reading your response on a post referenced by @Midavalo. Anyways, this set me down the right path, I think. I took your idea of clipping the transit routes to the polygons of interest; however, when I ran the Feature to Polygon tool some of my polygons were so tortured that it was really hard to find a clear way of extracting the features I wanted. So, I simply buffered the clipped routes by 1 meter then used the erase tool. I can't believe I didn't think of this before. I'd like to not remove that much of the polygon, but it should be fine. – jwx Jan 25 '17 at 18:59
  • Mark as solved it @klewis suggestion helped – FelixIP Jan 25 '17 at 23:52
