I need to extend the polygons in blue to match the red polygons using automation, since there are thousands of these. It seems like a simple thing to do, but I have not found a suitable way to accomplish it.

    What software and license level (if applicable) do you have at your disposal? What have you tried so far and what result did you get? – Michael Stimson Aug 9 '17 at 21:45
  • I am using ArcGIS Pro 10.4. I have tried Extend Line after converting the blue polygons to lines. I have also tried Snap and making a buffer so the red polygons intersect the blue, somehow I thought that would help. That white space with a cul de sac at the end is the roadway, I really just need the blue boundary to align with it. So the red polygons are just the space in between, I may or may not need those to achieve the ultimate goal of aligning those blue polygons... – Rachel Shaffer Aug 9 '17 at 21:57

    This is indeed a tricky problem, to extend the lines to the cul-de-sac you would need to convert to line both feature classes and remove the common line, you could probably do that on the blue polygon with an erase on a buffer of the red polygon bounding line then clip the blue polygons line, buffer and erase the red polygon lines leaving both ends open, merge erased red & blue boundaries and use extend line resources.arcgis.com/en/help/main/10.2/index.html#//… then feature to polygon with centroids of blue... some manual editing/checking will be needed. – Michael Stimson Aug 9 '17 at 22:04

    I would hardly classify this as a "simple thing". It might seem simple for a human, but teaching a computer to do such a task will quickly expose complexities that approach an NP-Complete problem. – Vince Aug 10 '17 at 0:17
