Get Sketch Arc Data Example (C#)

This example shows how to get sketch arc data.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified document template exists.
// 2. Open an Immediate window.
//
// Postconditions:
// 1. Creates a new model document with a sketch of an open arc.
// 2. Inspect the Immediate window.
//
// NOTE: Because the model is used elsewhere, do not save changes.
