Creating Perspective Sections and Adjusting Camera Lens

1. In Plan, place a camera: View → 3D View → Camera.
2. Open the resulting 3D camera view.
3. Ensure the view is in Perspective.
4. Use Orient to View → Section to create a perspective section.
5. Adjust the Section Box to control cut depth.
6. Clean the view with VV/VG and Graphic Display Options.
7. Adjust Focal Length in the Navigation Wheel settings:
   • Higher focal length = flatter.
   • Lower focal length = more dramatic.
8. Save + rename the view and add to sheets as needed.

Note:
Perspective sections are ideal for spatial explanation and system coordination.
