Scale Used In Engineering Drawing

An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings.

Scale used in engineering drawing. This is the same drawing of the v block but at a scale of 1 2. When the drawing ages the engineer s scale shrinks and may not give accurate results. Then consider the reduction scale ratios in required format 1 2 1 5 etc. Blueprint drawings are typically drawn in.

1 20 and 1 40 scales are used for working plans. We use the enlarged scales for very small objects. 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. An engineering drawing is a type of technical drawing that is used to convey information about an object.

Example blueprint drawing scale 1 50. The graphical scale is drawn on the drawing. To scale a si drawing. 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.

Engineers typically use this scale for drafting and blueprint creation. Where the denominator is the number after the colon. More than one scale may be used on a drawing. 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.

Find an even whole number dimension on the drawing and check it with the scale. The number 1 means 1 graduation of 1 inch represents 1 foot. Changes will be only at the point of drawing. No changes in dimensions.

You can use this technique to check if you have the scale set correctly for your printed drawings. Multiply the measurement on the drawing with the denominator. Typically in civil engineering applications 1 10 1 10 is used exclusively for detail drawings. Hence graphical scale is used as the drawing shrinks the scale will also shrink.

But the change is while representing the drawing on a sheet. The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization. Check the drawing scale in the example at the left the scale is 1 1 0 use a engineering scale. 1 60 is normally used only to show large areas of a project.

Graphical scales are used in survey maps. 1 4 or 1 8 imperial units us scales.
