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

This example demonstrates firing an undo post-notification event.

// --------------------------------------------------------------------------

// Preconditions: Open:

// <SolidWorks_install_dir>\samples\tutorial\api\cstick.sldprt.

//

// A cut-extrude feature is created on the top face of the

// candlestick. The feature is then undone and an undo

// post-notification event is fired. A message box is displayed

// notifying you of the event. Click OK to close the message box.

// The cut-extrude feature and all absorbed features are deleted.

//

// Postconditions: None
