Smoothing Tool in Advanced Editor

Problem:
You have many polygons that are not smoothing and for aesthetics they need to be smoothed.

Solution:

1. Start an Edit session for the shapefile that needs to be smoothed. 
2. Select the individual polygon or multiple polygons that need to be smoothed.
   
3. Add the Advanced Editor toolbar.
4. Select the last icon, Smooth. 
   
5. A dialog box will appear and you will choose a positive number for the offset. This number will depend on the polygon. For this example I choose 1, but I have also done 10 to make the polygon smooth. 
   
6. Your final result should look smooth. If you select too high of an offset, this can drastically change the shape of your polygon. As you can see below the shape is still the same but the rough edges are gone.
