1 - Dịch chuyển các điểm Chiều cao và Độ dày để thay đổi thiết diện.

2 - Thao tác trên đa diện bằng cách rê một đỉnh bất kì trong số các đỉnh.

3 - Đặt kiểu bề mặt của đa diện là "Rỗng" để có các cách nhìn khác nhau của thiết diện.

4 - Khởi động hoạt náo (bảng chọn Cửa sổ/Hoạt náo) để quan sát sự biến đổi của thiết diện tương ứng với sự thay đổi chiều cao.
