Insert MidSurface in Component (C#)

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

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

// Preconditions:  Assembly is open in SolidWorks and must contain at least

//                 one component. The component must contain a solid body.

//

// Postconditions: A midsurface feature is inserted in the component.
