Creating rectangle over a buffer circle with specified angles/rotation?

DavidBurt1 — Sat, 01 Dec 2012 23:39:23 GMT

Hello everyone,

I have a layer that is a circle buffer around a point. What I want to do is create a rectangle around the circle, but have every rectangle be perfectly lined up N/S (0degrees of angle/rotation). I have tried using Minimum Bounding Geometry, but the rectangles are all rotated a little different each time instead of all being the same. Is there any way to do this?

Thank you for the help.

What you want is Feature Envelope to Polygon - this geoprocessing tool requires the ArcInfo (Desktop Advanced) license---

Or, if you don't have that license level for Desktop, then there is a 'square buffer' script example here (scroll down to "Example: Using SearchCursor and InsertCursor to create square buffers")---

The ENVELOPE option in Minimum Bounding Geometry tool should give you the N-S squares for the circular buffers; this option requires the ArcInfo (Desktop Advanced) license.
