[GIS] Circular insets in ArcGIS

Question

Looking for a way to add an AutoCad-type circular inset in ArcGIS 10.1. Have tried many different methods but the best we have been able to do is shown here

using "insert picture" after various image/raster processes.

Answer 1

You can do this in the Data Frame Properties for the inset window, under the Frame tab, use the Rounding setting. For a circle, just start with a square data frame and then set the rounding to 100%.
