Undo Hidden Component and Fire Undo Post-Notify Event Example (C#)

This example shows how to fire an undo post-notification in an assembly document.

//--------------------------------------------------------------------------
// Preconditions: Open public_documents\tutorial\smartcomponents\stepped_shaft.sldasm.
//
// Postconditions:
// 1. Selects and hides the base-plate<1> component.
// 2. Undoes the hiding of the base-plate<1> component.
// 3. Fires a post-notification indicating that an undo action occurred.
// 4. Click OK to close the message box.
//
// NOTE: Because the assembly is used elsewhere, do not save changes.
