I'm manually editing some polygons and for the polygons that share a common boundary, I need them to have the exact common boundary and I cannot get them to close the gaps.
I've tried using the Align Features tool Modify Features tool reference—ArcGIS Pro | ArcGIS for Desktop but it is not working... Instead of closing the gap, I end up with a bigger gap or only the gap, opposed to removing the gap and having a common boundary as in the rightmost par of the clipping: (different results based whether I start from the left or the right)
PS. I have the Map Topology ENABLED
Any ideas on how to make them share a common boundary?

Hey Hector,
Have you tried the Eliminate tool? It is supposed to close the slivers between polygons. I also found this post here with methods that could be useful for your situation. Hope this helps!
Hi Hector,
I would recommend creating a geodatabase topology. With a topology you can set the cluster tolerance. Any vertices less than the cluster tolerance will snap together.
looks just like the tool I need to use. I just need to figure out how to use it in ArcGIS Pro since it is only available via Python...

Hector, you can still use arcmap for data preparation, you should realize that the transition is in progress

many thanks for your valuable ideas! It got me on the right direction.
I managed to make it a topology layer and then using the Align Edge Align topology edges—ArcGIS Pro | ArcGIS for Desktop tool. Quite magical, but manual, since there are only a few Slivers I needed to get rid of, it was no problem at all.
I inherited layers that divided each county into "Routes". The previous work had no precision and the routes had gaps and overlaps. I tried several different techniques and found the following to be most expeditious and precise. I used the Align Tool, but it removed some curves and precise angles that I had put much time into creating.
Assuming the drawing shows a Northern Polygon and a Southern Polygon being separated by a Road.
Note: for further precision, divided highways and interstates can be used by selecting the North/South or East/West line or create a copy then use Collapse Dual Lines To Centerline Tool to create a single line down the middle for splitting polygons.
