We provide QuickScale software for taking measurements off pdf drawings. QuickScale will calibrate your drawing when you have no scale so that you can print to scale. Enter the scale of the drawing and 1 known site measurement, or if there is no scale, plot 2 known site measurements. You can then take off any measurement or any shaped area from your PC. Print to scale on A3 or A4 even if the original was created in A0. QuickScale works on any pdf - drawings, scanned drawings, photos and maps. We have a free download on www.anyscale.co.uk
