Create Loft Body Example (C#)

This example shows how to create a loft body.

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

// Preconditions:

//       (1) Part document is open.

//       (2) Two closed sketches representing the profiles for the loft body exist.

//       (3) One curve representing a guide curve for the loft body exists.


// Postconditions: Loft body is created and displayed.
