I had to make some minimum bounding circles from a set of points in ArcGIS. After some searching i came across a very useful script by Dan Patterson. Actually it comes as a set of scripts in a toolbox. Ready to be imported into ArcGIS 9.3.
The toolbox has scripts for generating convex hull, minimum area bounding rectangle, minimum area circle and extent polygons.
You find it here.
