Engineering Drawing Scale

The number 1 means 1 graduation of 1 inch represents 1 foot.

Engineering drawing scale.

Blueprint drawings are typically drawn in. Technical drawing has existed since ancient times. Complex technical drawings were made in renaissance times such as the drawings of leonardo da vinci modern engineering drawing with its precise conventions of orthographic projection and scale arose in france at a time when the industrial revolution was in its infancy. 1 4 or 1 8 imperial units us scales.

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. 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 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. To scale a si drawing.

An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings. 1 8 1 0 invert the fraction and multiply by 12. To put simple it is the ratio of your drawing s size to the size of actual object. 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.

Multiply the measurement on the drawing with the denominator. 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. Select the desired scale. 8 1 x 12 scale factor 96.

Usually the word scale is used for an instrument used for drawing straight lines. 20 x 12 scale factor 240 architectural scales. Most of engineering students get confused about scale reduction and enlargement. It can be indicated in two different ways.

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. To convert an engineering drawing scale to a scale factor. Use a engineering scale.

First check the drawing scale is accurate as above. Select the desired scale. A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length. 1 20 multiply the feet by 12.

If the object you sketch is 50 cm 500mm long but your drawing is 5cm 50mm long scale is 1 10. To convert an architectural drawing scale to a scale factor. Example blueprint drawing scale 1 50.
