Translations:Drawing Template HowTo/72/en

Page Size
In order to allow a final drawing to be printed in the right scale, the template must contain it's dimensions in real world units. Otherweise the whole drawing page would be printed scaled down by a factor of 3.54 (90(px/in)/25.4(in/mm) Inside the the  -Tag the unit "mm" is added to the width and height fields. And a viewBox Atrribute has to be added. The viewBox ranges from 0 0 to the width and height of the template. This way the SVG user unit (px) is redefined to be 1mm long. In consequence programms linke inkscape will the able to print a resulting drawing up to scale. Current versions of inkscape handle this information very badly. Inscapes effectivly rescales the whole document to 90dpi. After editing a template in Inkscape, it would have the same real word size on its own but elements of the drawing would be scaled down by a factor of 3.54. Therefore it's recommended to remove the "mm" from the width and height attributes before opening an existing template in inkscape and recreate the units and viewBox attribute afterwards.
