Configuration of CustomUnits, Units and UnitsScale does not solve the problem of incorrect drawing scale. If incorrect drawing scale is imported and you want to add additional dimensions, they are incorrect in dimension value or text size. Most drawings cannot be plotted if drawing scale is 1:1 because the drawing size is to big. The dimension values, dimension text sizes, text sizes and text positions becomes incorrect if chancing drawing scale after import. This behavior can be avoided if customizable drawing scale will be accepted in "dxfdwg.exe".
