Selectively and Transparently Section a Section View Example (VB.NET)

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.
