Show an Object in the ShapeSheet Window
Microsoft Visio objects are stored internally as a set of formulas. You can view a Visio object in the ShapeSheet window to see and edit the underlying formulas that determine its appearance and behavior.
For details on how to show a specific object in the ShapeSheet window, click an element in the following list.
Show a shape, group, guide, guide point, or foreign object
Select the object.
