Determines the number vertical units inside the SURFCAM window at a Set Scale value of 1.
Example
Suppose you choose Inch Units, set the Scale to 1, as shown above, and the Width to 7.5. In this case, the SURFCAM screen covers 7.5 inches vertically, regardless of the window size. That is, if you physically measured the SURFCAM screen with a ruler, it would not necessarily be 7.5 inches high, but a drawing 6 inches high would easily fit in the SURFCAM window height.
The default values of 10 Width and 7.5 Height represent a normal screen ratio. If your monitor distorts the width or height of SURFCAM models, use the Width and Height values to correct the distortion. If your monitor is does not distort SURFCAM models, you must maintain a ratio of 10 Width to 7.5 Height to avoid distortion, for example, 100 Width and 75 Height.
