Hie Uwe, if you activate the button that takes the current value for seting up the smallest/largest scale you will see that RealScale should be taken (if i remember correctly). I need to look where the hint comes from.. propabaly we forgot to change the language files here (it should be only u

Hi Uwe, There are two kinds of scale in JUMP. The internal scale is given by: internalScale = ModeViewWidth / PixelViewWidth. (typically units of meters/pixel) The internalScale is used to transform distance between model space and screen space (at a particular view's zoom level) via a simpl
