Create Local Curve-Driven Pattern Example (C#)

This example shows how to create a local curve-driven pattern feature.

//------------------------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified assembly document to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the assembly document.
// 2. Selects the component and edge for the
//    local curve-driven pattern feature.
// 3. Creates a local curve-driven pattern feature.
// 4. Gets values and settings of the local curve-driven 
//    pattern feature.
// 5. Examine the Immediate window and graphics area.
//
// NOTE: Because this assembly is used elsewhere, do not save
// changes.
