Get Face Hatch Data Example (C#)

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 public_documents\introsw\bolt-assembly.slddrw.
// 2. Select Section View A-A in the FeatureManager design tree.
// 3. Open the Immediate window.
//
// Postconditions:
// 1. Gets face hatch data.
// 2. Examine the Immediate window.
