Selectively and Transparently Section a Section View Example (C#)

This example shows how to selectively and transparently section a section view.

//-------------------------------------------------------------------------
// Preconditions: Verify that the assembly to open exists.
//
// Postconditions:
// 1. Opens the assembly.
// 2. Selects the component for selective sectioning.
// 3. Selects the components for transparent sectioning.
// 4. Selects the planes for sectioning.
// 5. Creates the SectionViewData object.
//    a. Sets the section method to zonal.
//    b. Sets to cap the sections.
//    c. Sets to generate a graphics-only section view.
//    d. Enables selective sectioning.
//       1. Sets the component selected in step 2 for selective
//          sectioning.
//       2. Sets the intersection zone.
//       3. Sets to exclude the component set in step 5.d.1 from
//          selective sectioning.
//    e. Enables transparent sectioning.
//       1. Sets the components selected in step 3
//          for transparent sectioning.
//       2. Sets to include the sectioned components set in step 5.e.1
//          in transparent sectioning.
//       3. Sets the level of transparency.
// 6. Creates the section view.
// 7. Examine the graphics area.
// 8. Click Section View twice in the Heads-Up View toolbar and
//    examine the Section View PropertyManager page.
//
// NOTE: Because the assembly is used elsewhere, do not save changes.
