how to use a scale ruler 1:20

Before he retired he was, quite literally, a ‘rocket scientist’ and worked as an aeronautical engineer in the aerospace industry. How to use a scale ruler to read and draw architecture and engineering scaled drawings. For example, lets imagine we have a drawing at 1:50, but we want amend the scale, to show that drawing at 1:200. i have a CAD drawing that is drawn in Meters (CAD Unit is meter) But one can’t buy a scale ruler which deals clearly with these scales. The only freedom from scale in these cases is perhaps the choice of which details of decoration, texture or colour are really significant. I can’t figure out what the one scale factor is that I can use to scale the 1:1 drawing by to get it to come in to the cover sheet at the right scale. In architecture, we use a collection of standard scales to represent our designs. The scale shows 150 to 1. This is useful if you have imported a drawing at a different scale. Thanks! I would recommend that if you can’t get the ‘quality’ scale ruler in exactly the scale you want it’s better to go for a cheaper metal one. This is true for all of the numbers on the engineer’s scale. the use to which it’s going to be put. Everything is divided by the same amount .. in this case by 2. If it is just the paper size you wish to change, then you can use the paper size converter. So, if you want to increase the scale of a drawing using a photocopier, but want to increase it to a standard scale (1:10 for example) then you must use the percentage factors for converting scale. Check to see if the drawing lines are still in metres, if they are – Then go into your paper space, select all, type SCALE, ref point 0,0,0 and scale factor 1000. the purpose, the context. For every ‘certain number’ of eggs in a pudding mix there has to be another ‘certain number’ of spoonfulls of flour. to the main point here, if you are working in feet and inches for whatever reason, you have to use a scale that makes sense with, i.e. Hi there, When I’ve asked why, no one has given me a convincing answer!

The site drawing is referenced on my cover sheet. Technical Drawing: Construction Drawings   In Part 5 of the Technical Drawing series we are going to explore construction drawings. Sometimes this is integral to the medium. Dividing 100 by 0.4 gives 250, which is right as 250% on the photocopier. Any advise? Hopefully this will work. Above I’ve described 1:2500 as a ‘smaller’ scale than 1:25 .. which is correct! Having the formula above, together with either a standard scale ruler (or clearly defined normal ruler) and access to a photocopier, means that one can easily create one’s own custom scale ruler no matter how ‘peculiar’ the chosen scale might be. Theatre design models in this country are always 1:25 scale. In everyday life we don’t have to be conscious of exactly how much smaller than life-size that image is, but in a way our unconscious mind is and uses that calculation to help judge how far away that object is. .. and I wait patiently for more information to come, i.e. .. are used to these. When you are reading plans, you establish the scale of the drawing or plans, and select that scale on your ruler, you are then able to measure the lines using the correct scale. Programs such as Revit, AutoCAD, ArchiCAD and many more, allow you to draw up your designs at 1:1 scale, that is real life size, and produce drawings or plots of these designs at an appropriate scale for the paper size you have selected. For these, all details could be considered ‘significant’ .. the disarray of books on a central table, the crumbly matte surface of an ancient wall or the right kind of curve on a tiny rococo chair .. because a set design is the sum of many visual decisions working together. I’m still looking around for the ideal material in translucent greens which can be chopped or granulated but in the meantime my preference is using crushed eggshell shown below which, once applied, can be tinted with watercolours. Required fields are marked *. A drawing at a scale of 1:10 means that the object is 10 times smaller than in real life scale 1:1. I feel they illustrate how one can be free and ‘painterly’ in tackling the essentials of surfaces and significant detail, but still achieve a result that is as a whole unquestionably real! When working in CAD you can let the software do some of the hard work for you by making use of the paper space option to create layouts. – first of all is this a correct scale? I’ve got a question regarding the scale on a view port. Buy a scale rule that shows 1:20, these are often triangular, with 1:100, 1:50, 1:20 etc. Using a scale rule is pretty easy when you know how. can be taken directly from the groundplan when drawing up, which is important because it avoids the possible mistakes that occur when elements have to be drawn in separation. It depends on the purposes of the model i.e. Any obstructions such as pillars, anything jutting out from the walls and even the smallest steps or variations in the floorspace need to be faithfully rendered so that they are not overlooked when filming is being planned. you’re seeing it ‘half as big’ or ‘half-size’ or even ‘twice smaller’! As ‘luck’ would have it this can be used for 1:25 work in place of the proper scale ruler because the calibrations work out the same .. one just has to think of it as representing centimetres rather than metres. As in a good ‘Impressionist’ painting, scale and proportion form a disciplined framework upon which surface qualities can be played upon more suggestively. In any event it’s useful to have a regular rule included ). 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.e. The image above shows an example of a drawing set with different scales to demonstrate different aspects of the design. But returning ..finally!.. If the plan tells you the door width, you can work out what units the plan it in. I have a 2D site drawing drawing 1:1. 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. You could also say, 1 unit in the drawing is equal to 100 units in real life. I’ve always felt, and said, that clever suggestion often has more power to convince than slavish depiction .. and it can be a lot quicker! So, if a drawing is at 1:50 in cm, 1cm in the drawing will be equal to 50cm in real life. To do this we would make sure the dimension ratios of the image are locked, and proceed to type 50% into the size box.

When a drawing is described as ‘to scale’, it means that each element in that drawing is in the same proportion, related to the real or proposed thing – it is smaller or indeed larger by a particular percentage. Although I know this is nothing compared to calculating trajectories I needed his clear perspective. But no, this really isn’t that simple or comfortable! A word about ‘describing’ scales i.e. I say more about the purposes and the benefits of models in theatre design in my post Why make models? In any event it’s useful to have a regular rule included ). What would have occurred quite naturally would be to make one inch, half an inch or a quarter-inch on their measuring ruler represent ‘1 foot’ giving the scales (as we might describe them now) 1:12, 1:24, 1:48 and 1:96. Hi, can someone tell me how a scale ruler works it has1:20 1:25 1:50 1:75. i want to do some drawings of 1:000 & 1:20, is it just a case of on the 1:20 for example 1" = 20" & 1ft = 20 ft & 1metre = 20 metres. 1:35 to 1:50 and 1:10 to 1:50 I’m bringing in the pdf drawings into illustrator and then tracing them so they can all be viewed in at the same proportional scale, thank but i can’t download this pdf for scales. A lot of people find it no problem to mentally switch, but it’s certainly much easier to misread or make other mistakes using one of these and it certainly doesn’t help that there are also usually two different scales cohabiting the same edge, as you can see here.
