Insert MidSurface in Component Example (C#)

This example shows how to insert a midsurface feature in a component.

//---------------------------------------------------------------
// Preconditions:
// 1. Open an assembly that contains at least one component
//    that contains a solid body.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Inserts a midsurface feature in the component.
// 2. Gets the number of faces in the midsurface feature.
// 3. Examine the Immediate window.
// 4. Expand the component in the FeatureManager design tree
//    in which the midsurface feature was inserted to
//    verify step 1.
