Get Solid-fill Hatch Information Example (C#)

This example shows how to get information about solid-fill hatches in a detail view in the current drawing sheet.

// Preconditions:
// 1. Open public_documents\introsw\bolt-assembly.slddrw.
// 2. Verify that c:\temp exists.
// 3. Create a detail view of Section View A-A:
//    a. Click Insert > Drawing View > Detail.
//    b. Sketch the profile for the detail view of Section View A-A.
//    c. Move the pointer while dragging drawing view. When the view
//       is where you want it to be, click to place the view.
//    d. Click OK to close the Detail View PropertyManager page.
// 4. Right-click the detail view in the drawing to open the
//    Area Hatch/Fill PropertyManager page.
//    a. Clear the Material crosshatch check box.
//    b. Select Solid.
//    c. Click OK.
// Postconditions:
// 1. Traverses the drawing views.
// 2. Gets data about the solid-fill hatches in the detail view.
// 3. Open c:\temp\SolidFillData.txt in a text editor and examine the
//    contents of the file.
// NOTE: Because the drawing is used elsewhere, do not save changes.
