Hide and Show Sketches Example (C#)

This example shows how to hide and show sketches in a model.

//---------------------------------------
// Preconditions: Run the macro.
//
// Postconditions:
// 1. Opens a new part document and
//    creates two sketches.
// 2. Selects one sketch and hides it.
// 3. Examine the graphics area to verify 
//    and press F5.
// 4. Selects the hidden sketch and shows
//    it.
