How do scale rulers work




















Some sets with multiple rules can include up to 16 scales. These are typically 12 inches long and you can find a remarkable variety to choose from: plastic scales, others of solid aluminum, and ones with color-coded grooves. You can also download a simple printable version from Archtoolbox. This makes it quick and easy to draw different prints at different scales, as well as interpret different prints at different scales. MT Copeland offers video-based online classes that give you a foundation in construction fundamentals with real-world applications.

Both clearly show the scaled size of 1metre, 2metres and so on..

Both clearly indicate 50cm divisions and the smaller divisions after that represent units of 10cm. The very smallest divisions within those.. With the right scale ruler to assist, working in scale really should be as simple as reading from a regular tape measure.

But unfortunately one might have to hunt around a bit for the right scale ruler to use. Many art or graphic supply shops stock them but there may be more demand for the type shown above which is also available in the triangular form which is calibrated for working in much smaller scales. The numbers along the scale above are the number of metres represented and the smallest divisions therefore represent 2metres. A scale model of an 8 metre long fire engine will be much smaller than a model of the same.

But the fire engine may be part of a modelled street which conveys a larger area than a model can. To be fair, there are scales that are more prescribed or advantageous in certain circumstances. Theatre design models in this country are always scale. If any smaller they would lose in terms of presence and detail. What I mean is that, there may be conditions imposed on the scale one chooses but otherwise one has the freedom to choose the most appropriate scale oneself. Best of all is if groundplan and elevations can be arranged on the paper like a hinged box, with the groundplan in the centre and walls folded flat around it.

This also means that wall lengths and positions of windows, doors etc. But the point here is that, although there are common practises tried, tested and above all familiar methods that it is often advisable to go along with, in the end any practical solution that the one doing the work making the drawing or the model comes up with including using a different scale if need be should be acceptable if the end result communicates clearly!

This measurement system is known as Imperial. If you live in the UK, on the other hand.. Politicians are concerned that young people are becoming increasingly confused.. Others suggested to me a while ago now that it made sense because structural timber and plywood sheets for building are still conceived in terms of feet and inches i. But, so what? But returning..

Because there are 12 inches in a foot the only scales that will work smoothly will be those that are easy multiples of divisions of It would never have occurred to a Victorian craftsman to work in , , or Scaled measurements can therefore be measured using a regular ruler, up to a point, and as long as the inches on the ruler are divided into quarters and eigths.

But when I ask, as a bit of a test, whether anyone can tell me what percentage of reduction is needed on the photocopier to convert a to I can almost hear all minds in the room turning to jelly. If I ask what the percentage of reduction is for changing a drawing to a there is usually more response.

Divide 2 into and we get 50, which can now be used as a percentage. So does this work for any set of numbers or is it just a lucky coincidence? Going back to the previous question, converting to If is then divided by 2. Does it work the other way? Enlarging a drawing to make it scale?
