Engineering Drawing Scale Ratio

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.

Engineering drawing scale ratio.

To convert an engineering drawing scale to a scale factor. 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. 1 20 1 50 or 1 100 si units or. Blueprint drawings are typically drawn in.

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. Example blueprint drawing scale 1 50. To convert an architectural drawing scale to a scale factor. Scale the original border down by this amount and your scale is changed.

This is an online scale length converter that calculates the actual length and the scale length according to the scale ratio. 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. With visual graphic and formula it let us more easily understand the calculation process and the result. Working out the scale.

Where the denominator is the number after the colon. An engineering drawing is a type of technical drawing that is used to convey information about an object. 20 x 12 scale factor 240. A scale is shown as a ratio for example 1 100.

Select the desired scale. 1 20 multiply the feet by 12. Aaa drafting using a scale to read an engineering drawing. 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.

Scale ratio could be set by yourself supports different length units including imperial units and metric units. It can be indicated in two different ways. A drawing at a scale of 1 100 means that the object is 100 times smaller than in real life scale 1 1. 8 1 x 12 scale factor 96.

A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length. To scale a si drawing. Select the desired scale. 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.

The difference between the ratio numbers represents the factor by which the scaled image is enlarged or reduced. Scale drawings show an image either reduced or enlarged in size. Most of engineering students get confused about scale reduction and enlargement. Multiply the measurement on the drawing with the denominator.
