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.

No changes in dimensions. Multiply the measurement on the drawing with the denominator. You can use this technique to check if you have the scale set correctly for your printed drawings. 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.

Example blueprint drawing scale 1 50. An engineering drawing is a type of technical drawing that is used to convey information about an object. The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization. But the change is while representing the drawing on a sheet.

We use the enlarged scales for very small objects. These is used to locate a huge drawing in a particular sheet. 1 4 or 1 8 imperial units us scales. This is the same drawing of the v block but at a scale of 1 2.

Changes will be only at the point of drawing. When the drawing ages the engineer s scale shrinks and may not give accurate results. Where the denominator is the number after the colon. In this case all the scales used on the drawing should be indicated.

Graphical scales are used in survey maps. The graphical scale is drawn on the drawing. 1 20 1 50 or 1 100 si units or. The number 1 means 1 graduation of 1 inch represents 1 foot.

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. Hence graphical scale is used as the drawing shrinks the scale will also shrink. Engineers typically use this scale for drafting and blueprint creation.

Blueprint drawings are typically drawn in. Then consider the reduction scale ratios in required format 1 2 1 5 etc. 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.

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. 1 20 and 1 40 scales are used for working plans.
