Get Structural Member Body Sketch Segments Example (C#)

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\api\weldment_box3.sldprt.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Gets the feature definition of Structural Member1.
// 2. Selects body, Structural Member1[1].
// 3. Gets the number of sketch segments that define the path of the
//    selected body.
// 4. Examine the Immediate window.
//
// NOTE: Because the part is used elsewhere, do not save changes.
