Exploring CINEMA 4D R16 Studio Interface - MAXON CINEMA 4D R16 Studio: A Tutorial Approach - page 4

Figure 1-2 The default interface of CINEMA 4D R16 Studio
When you start CINEMA 4D, the Perspective viewport is displayed by default, as shown in
Figure 1-3. This viewport displays objects from a perspective camera. You can also display
other viewports such as Top, Right, Bottom, and Front in the work area. These viewports
display objects from orthographic camera view and do not display the perspective view.
To switch to the 4-view viewport arrangement, hover the cursor over the Perspective view-
port and then press the middle-mouse button once. If you need to maximize any of the four
viewports, hover the cursor over the required viewport and then press the middle-mouse
button once.
