Create and Modify Distance Chain Pattern Feature Example (C#)

This example shows how to create and modify a distance chain pattern feature.

//--------------------------------------------------------
// Preconditions:
// 1. Verify that the assembly to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified assembly.
// 2. Selects entities to create a distance chain pattern feature.
// 3. Creates the distance chain pattern feature.
// 4. After examining the graphics area and FeatureManager design
//    tree, press F5.
// 5. Modifies the distance chain pattern feature.
// 6. Examine the graphics area to verify step 5.
// 7. Examine the Immediate window.
//
// NOTE: Because the assembly is used elsewhere, do not save
// changes.
