SmartShapeRenumber allows you to renumber group shapes where the number of the shape is in a separate location from the shapes text.
In this example it will enter the number of the shape in the top right portion of the main shape.
SmartShapeRenumber also supports numbering simple shapes where the number is part of the text of the main shape.
SmartShapeRenumber also supports prefix values if you need them.
Visio's standard renumbering tool supports the prefix concept but only applies numbers to the main text of the shape and will not put number a group shape.
Using the Tool
Press the SmartShapeRenumber shortcut key (control+N).
The first time SmartShapeRenumber is used, you can add a prefix that will apply to all numbered shapes on the current page.
Leave this blank if you dont have a prefix.
You now enter the value to start numbering from.
SmartShapeRenumber finds the number of the first shape as a default, so if you are renumbering, start with the first unchanged shape.
The shapes in the selection are renumbered in the order that they were selected.
