The 3D viewer provides two different cameras.
This camera allows you to quickly go around the layout using the mouse only.
The camera is aimed at one point, initially at the center of your layout, the pivot point.
•Use the mouse wheel to zoom in and out
•Hold down the left mouse button and move the mouse to move around the focal point. The pivot point remains the same.
•Hold down the right mouse button and move the mouse to pan. This changes the pivot point.
This camera works much like the camera in a 'First person shooter' type of game. You can move around, and just get to see whatever you look at. You need to use the mouse and the arrow keys on your keyboard.
•Hold down the left mouse button and move the mouse to change the viewing direction.
•Use the arrow keys to move forward, backwards, and sideways. Hold down the right mouse button to double your speed.
Tip: In case you get lost, click the Camera back to starting point button.
