All copies of drawings created or modified by printing (as distinct from plotting), photocopying, faxing, or turning into a PDF almost certainly are not accurate. A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length two common examples are an architect's scale and engineer's scale. While most original plots from a CAD file should be accurate (though human mistakes can and do happen), anything which has been plotted to "fit" the sheet of paper, rather than to a specific scale, is likely to be mis-scaled. This can be done by checking the measurement of a dimensioned object or an object of known size.ĭrawings can be inaccurate due to any form of copying or processing. 0 1 2 3 4 5 6 7 8 9 10 6 11 12 cm in 1 0 2 3 4 5 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 Click, Print, Rule Ruler.

You should always check that the document was printed out accurately before making measurements and conversions. Colley describes how to use the metric ruler to Aiken Technical College 112 Biology students.
So, not only should you verify the scale of the drawing, but you should verify its accuracy. The printer may rescale the image to fit the different sized paper, which will result in an inaccurate print-out.Īll of your measurements taken from these printed copies would be incorrect. There may be slight size deviations due to manual measurement, different measuring methods and. Making accurate measurements is very important The first step in measuring the length of an object using a ruler is making sure that you're using the correct ruler. Letter sized paper that is 8.5 inches x 11 inches (216 mm x 279 mm) and tried to print it on metric A4 paper that is 210 mm x 297 mm (8.27 inches x 11.7 inches). Brass Vernier Caliper Ruler 0-100mm Double Scale Vernier. Also, check that the printed physical scale of the drawing is correct.Ĭonsider what would happen if you took a drawing that is the correct scale on a piece of U.S.
