Scale Used In Engineering Drawing

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

Scale used in engineering drawing.

The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization. When the drawing ages the engineer s scale shrinks and may not give accurate results. 1 60 is normally used only to show large areas of a project. Changes will be only at the point of drawing.

An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings. 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. This is the same drawing of the v block but at a scale of 1 2. The graphical scale is drawn on the drawing.

Example blueprint drawing scale 1 50. In this case all the scales used on the drawing should be indicated. 1 20 1 50 or 1 100 si units or. We use the enlarged scales for very small objects.

These is used to locate a huge drawing in a particular sheet. 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. Hence graphical scale is used as the drawing shrinks the scale will also shrink. Graphical scales are used in survey maps.

More than one scale may be used on a drawing. But the change is while representing the drawing on a sheet. Find an even whole number dimension on the drawing and check it with the scale. Blueprint drawings are typically drawn in.

Then consider the reduction scale ratios in required format 1 2 1 5 etc. Where the denominator is the number after the colon. To scale a si drawing. 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.

No changes in dimensions. Multiply the measurement on the drawing with the denominator. An engineering drawing is a type of technical drawing that is used to convey information about an object. Typically in civil engineering applications 1 10 1 10 is used exclusively for detail drawings.

Engineers typically use this scale for drafting and blueprint creation. 1 4 or 1 8 imperial units us scales.
