Get Components in Drawing View (C#)

This example shows how to get the components in a drawing view and how to change their line font styles.

//------------------------------------------------------------------
// Preconditions:
// 1. Drawing document opened by the macro exists.
// 2. Drawing view is selected.
// 3. Open the Immediate window.
//
// Postconditions:
// 1. Specified drawing document is opened.
// 2. Drawing View1 is selected.
// 3. Gets the root and children components for Drawing
//    View1.
// 4. For each component:
//    a. Prints whether a drawing component is selected,
//       the name of the component, and the name of the
//       configuration to the Immediate window.
//    b. Disables the use of the document defaults for the
//       the component's line font style.
//    c. Sets new line style and line thickness for the component's
//       visible edges and prints the new settings and values to
//       the Immediate window.
//    d. Prints the file name of the component to the Immediate window.
