Engineering Drawing Scale

If the object you sketch is 50 cm 500mm long but your drawing is 5cm 50mm long scale is 1 10.

Engineering drawing scale.

Select the desired scale. Multiply the measurement on the drawing with the denominator. 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. Where the denominator is the number after the colon.

First check the drawing scale is accurate as above. 1 20 multiply the feet by 12. 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. 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.

8 1 x 12 scale factor 96. 1 20 1 50 or 1 100 si units or. Example blueprint drawing scale 1 50. 20 x 12 scale factor 240 architectural scales.

Blueprint drawings are typically drawn in. 1 8 1 0 invert the fraction and multiply by 12. Usually the word scale is used for an instrument used for drawing straight lines. 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. 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. Select the desired scale. Most of engineering students get confused about scale reduction and enlargement.

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. 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. Use a engineering scale.

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

Technical drawing has existed since ancient times. 1 4 or 1 8 imperial units us scales. It can be indicated in two different ways.
