Engineering Drawing Scale Ratio

It can be indicated in two different ways.

Engineering drawing scale ratio.

To scale a si drawing. To convert an architectural drawing scale to a scale factor. 1 20 1 50 or 1 100 si units or. But actually in engineer s language scale means the proportion or ratio between the dimensions adopted for the drawing and the corresponding dimensions of the object.

Two common examples are an architect s scale and engineer s scale in scientific and engineering terminology a device to measure linear distance and create proportional linear measurements is called a scale. Aaa drafting using a scale to read an engineering drawing. To convert an engineering drawing scale to a scale factor. A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length.

A drawing at a scale of 1 100 means that the object is 100 times smaller than in real life scale 1 1. Scale drawings show an image either reduced or enlarged in size. Working out the scale. Select the desired scale.

1 8 1 0 invert the fraction and multiply by 12. Blueprint drawings are typically drawn in. The change between the original and the scaled drawing is generally represented by two numbers separated by a colon like 10 1 read as ten to one. An engineering drawing is a type of technical drawing that is used to convey information about an object.

The difference between the ratio numbers represents the factor by which the scaled image is enlarged or reduced. A scale is shown as a ratio for example 1 100. This is an online scale length converter that calculates the actual length and the scale length according to the scale ratio. Where the denominator is the number after the colon.

8 1 x 12 scale factor 96. 1 20 multiply the feet by 12. Scale is the ratio of the linear dimension of an element of an object as represented in the drawing to the real linear dimension of the same element of the object itself. Most of engineering students get confused about scale reduction and enlargement.

20 x 12 scale factor 240. Multiply the measurement on the drawing with the denominator. Scale the original border down by this amount and your scale is changed. Scale ratio could be set by yourself supports different length units including imperial units and metric units.

Select the desired scale. Usually the word scale is used for an instrument used for drawing straight lines. In the past prints were plotted on a plotter to exact scale ratios and the user could know that a line on the drawing 15mm long corresponded to a 30mm part dimension because the drawing said 1 2 in the scale box of the title block. The ratio and decimal numbers can be helpful if you are working in paper space and need to know what the scale factors are for window resizing in order to create the proper scale.
