Engineering Drawing Scale

Usually the word scale is used for an instrument used for drawing straight lines.

Engineering drawing scale.

For example with an engineering scale it is possible to manually create a drawing that is ten times larger or ten times smaller than the original that the engineer is drawing from. Multiply the measurement on the drawing with the denominator. To convert an engineering drawing scale to a scale factor. Blueprint drawings are typically drawn in.

Student performance objective given an architect or engineer scale and a set of scaled drawings you will be able to select the correct scale tool and interpret dimensions with 100 percent accuracy. 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. To put simple it is the ratio of your drawing s size to the size of actual object. It can be indicated in two different ways.

The number 1 means 1 graduation of 1 inch represents 1 foot. 20 x 12 scale factor 240 architectural scales. Where the denominator is the number after the colon. 1 20 1 50 or 1 100 si units or.

First check the drawing scale is accurate as above. 1 8 1 0 invert the fraction and multiply by 12. 8 1 x 12 scale factor 96. 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. If the object you sketch is 50 cm 500mm long but your drawing is 5cm 50mm long scale is 1 10. Technical drawing has existed since ancient times. 1 20 multiply the feet by 12.

The smallest division on the scale is 1 4 here the plate thickness is not dimensioned but the scale reads 2 divisions or 1 2 check several other dimensions on the drawing to be sure the drawing is to scale. Engineers typically use this scale for drafting and blueprint creation. Construction and fire protection equipment drawings must be interpreted with a high degree of accuracy. Select the desired scale.

An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings. 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. Select the desired scale. Example blueprint drawing scale 1 50.

To convert an architectural drawing scale to a scale factor. To scale a si drawing. A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length.
