Trim Sketch Entities Example (C#)

This example shows how to trim a sketch to a corner.

//---------------------------------------------------------------------------
// Preconditions: Ensure the specified template exists.
//
// Postconditions:
// 1. Opens a new part document.
// 2. Sketches some lines.
// 3. Examine the sketch, then press
//    F5.
// 4. Selects two lines and trims them
//    to a corner.
// 5. Examine the sketch to verify.
