Scale Used In Engineering Drawing

Find an even whole number dimension on the drawing and check it with the scale.

Scale used in engineering drawing.

Typically in civil engineering applications 1 10 1 10 is used exclusively for detail drawings. Then consider the reduction scale ratios in required format 1 2 1 5 etc. You can use this technique to check if you have the scale set correctly for your printed drawings. Hence graphical scale is used as the drawing shrinks the scale will also shrink.

The number 1 means 1 graduation of 1 inch represents 1 foot. 1 20 and 1 40 scales are used for working plans. But the change is while representing the drawing on a sheet. 1 4 or 1 8 imperial units us scales.

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. The graphical scale is drawn on the drawing. 1 60 is normally used only to show large areas of a project. Multiply the measurement on the drawing with the denominator.

More than one scale may be used on a drawing. Check the drawing scale in the example at the left the scale is 1 1 0 use a engineering scale. These is used to locate a huge drawing in a particular sheet. Example blueprint drawing scale 1 50.

In this case all the scales used on the drawing should be indicated. 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. To scale a si drawing. Where the denominator is the number after the colon.

Graphical scales are used in survey maps. This is the same drawing of the v block but at a scale of 1 2. An engineering drawing is a type of technical drawing that is used to convey information about an object. When the drawing ages the engineer s scale shrinks and may not give accurate results.

We use the enlarged scales for very small objects. Blueprint drawings are typically drawn in. 1 20 1 50 or 1 100 si units or. 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.

An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings. Changes will be only at the point of drawing.
