Combine Bodies Example (C#)

This example shows how to combine bodies in a multibody part.

//-------------------------------------------------------------
// Preconditions:
// 1. Verify that the part document to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified part document.
// 2. Selects two solid bodies.
// 3. Inserts a combine feature using the two selected
//    bodies.
// 4. Prints the type of combine feature to the Immediate
//    window.
// 5. Examine the Immediate window.
//
// NOTE: Because the part document is used elsewhere, do not
// save changes.
