Creating a minimum bounding rectangle
The Create Minimum Bounding Rectangle tool is used to create a minimum bounding rectangle based on the combined spatial extent or envelope of one or more selected features. The rectangle that is created is either a polygon or polyline feature, depending on the template you are using as the target.
For example, if you choose a polygon template as the active template, the result is a polygon that contains all the selected features:
|  | 
| A minimum bounding rectangle when the target is a polygon feature class | 
If you choose a polyline template as the active template, the result is a polyline feature that contains all the selected features:
|  | 
| A minimum bounding rectangle when the target layer is a polyline feature class |
