This example shows how to get the number of face hatches in a standard or derived (detail, section, projected, broken, etc.) drawing view and their data.

// Preconditions:
// 1. Open a drawing with drawing views containing face hatches.
// 2. Select a drawing view with a face hatch.
// 3. Open the Immediate window.
// Postconditions: Examine the Immediate window to see
// the results.
