3 ## This macro generates two views of the NA49 detector.
4 ##
5 ## To have a better and dynamic view of any of these pads,
6 ## you can click with the middle button of your mouse to select it.
7 ## Then select "View with x3d" in the VIEW menu of the Canvas.
8 ## Once in x3d, you are in wireframe mode by default.
9 ## You can switch to:
10 ## - Hidden Line mode by typing E
11 ## - Solid mode by typing R
12 ## - Wireframe mode by typing W
13 ## - Stereo mode by clicking S (and you need special glasses)
14 ## - To leave x3d type Q
