Scale Used In Engineering Drawing

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

Scale used in engineering drawing. Find an even whole number dimension on the drawing and check it with the scale. 1 60 is normally used only to show large areas of a project. More than one scale may be used on a drawing. Where the denominator is the number after the colon.

In this case all the scales used on the drawing should be indicated. But the change is while representing the drawing on a sheet. To scale a si drawing. 1 20 and 1 40 scales are used for working plans.

Increasing the drawing scale even more to 1 5 it becomes quite obvious how much extra area are displayed but again the cost is details that can be seen. Typically in civil engineering applications 1 10 1 10 is used exclusively for detail drawings. Example blueprint drawing scale 1 50. Then consider the reduction scale ratios in required format 1 2 1 5 etc.

Engineers typically use this scale for drafting and blueprint creation. The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization. Multiply the measurement on the drawing with the denominator. Blueprint drawings are typically drawn in.

An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings. No changes in dimensions. 1 4 or 1 8 imperial units us scales. Graphical scales are used in survey maps.

An engineering drawing is a type of technical drawing that is used to convey information about an object. These is used to locate a huge drawing in a particular sheet. 1 20 1 50 or 1 100 si units or. Hence graphical scale is used as the drawing shrinks the scale will also shrink.

Check the drawing scale in the example at the left the scale is 1 1 0 use a engineering scale. This is the same drawing of the v block but at a scale of 1 2. 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. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing usually a number of drawings are necessary to completely specify even a simple component.

You can use this technique to check if you have the scale set correctly for your printed drawings. When the drawing ages the engineer s scale shrinks and may not give accurate results.
