In studying engineering drawings, in addition to learning how to draw a shape object atu also learn how to put the measures in the engineering drawings. The accuracy of the size of objects and how objects include measures are very important and must be in accordance with the rules of working drawings. What is meant here is the size of the measure to declare the size of the actual length of the line is actually not the size or scale.
Size and absolute size of the lines included in the working drawings as a guideline for realizing the object, then the accuracy of the placement and size and line size should be easy to read and clearly translated in the manufacture of objects. Writing numbers to declare length, height, or width must also meet dtelah rules agreed in the working drawings.
Examples of writing numbers, line size, and the dividing line is shown in the following figure:
Line size on both ends is expressed by the corresponding arrows on the right indicate the dividing line. How to make the size of the line and arrows are as follows:
The length of the line that specifies the length of the size, determined by the size of the numbers on the line size. For horizontal stripes size numbers written above the line size, while for vertical lines (vertical) size numbers must be written on the left of the line and the size of the figure is written upright anyway.
To separate the lines of the horizontal size of a line drawing, it can be placed above or below the line drawing, the lines were to measure the vertical (upright), the line is placed on the left or right of a line drawing.
In the picture, there is sometimes a short line drawings, then the direction of the arrow line size should be inward, and when the lines short size so that the numbers can not be written size, then the number is written on the outside of the indicated by arrows.
For objects that have the shape of a circle, the size can be expressed with his fingers or diameter.
