Engineering Drawing Scale

20 x 12 scale factor 240 architectural scales.

Engineering drawing scale.

Example blueprint drawing scale 1 50. Most of engineering students get confused about scale reduction and enlargement. It can be indicated in two different ways. Multiply the measurement on the drawing with the denominator.

Where the denominator is the number after the colon. Blueprint drawings are typically drawn in. Select the desired scale. 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.

The number 1 means 1 graduation of 1 inch represents 1 foot. First check the drawing scale is accurate as above. To convert an architectural drawing scale to a scale factor. A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length.

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. 1 4 or 1 8 imperial units us scales. An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings. 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.

1 20 multiply the feet by 12. 8 1 x 12 scale factor 96. To convert an engineering drawing scale to a scale factor. Engineers typically use this scale for drafting and blueprint creation.

Select the desired scale. Construction and fire protection equipment drawings must be interpreted with a high degree of accuracy. Usually the word scale is used for an instrument used for drawing straight lines. 1 20 1 50 or 1 100 si units or.

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. To scale a si drawing. Use a engineering 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.

To put simple it is the ratio of your drawing s size to the size of actual object. If the object you sketch is 50 cm 500mm long but your drawing is 5cm 50mm long scale is 1 10. 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.
