I have a reference line retrieved from a raster image in the background that I know in real life measures 10 mm (l_ref
). I want to scale the whole picture so that everything has real dimensions.
I use the measuring instrument to get the length (l_mes
) then I do in my Mac shift+cmd+m scale proportionally and apply to each object separately 100/(l_mes/l_ref)
%.
When I measure again the line has the same length, I don't understand why. Is there a better way?
