Webto mark the centers of circles and the axes of symmetrical parts, such as cylinders and bolts. Break lines are used to show where an object is broken to save drawing space or reveal interior features. Break lines come in two forms: a freehand thick line, and a long, ruled thin line with zigzags.
Web3.2.2 Flatness - The flatness symbol appears as an oblique view of a square surface. See Figure 20.

Web11. apr 2011. · Here is how to calculate the flatness. Measure the thickness of the part. Let's say it was .497. From the maximum part thickness of .510, subtract the actual thickness. In our case we would get .013 and that is the flatness allowed at that thickness. If the part was made at its largest allowable size, .510, there would be not flatness allowance.

The datum is a theoretical reference, but the physical surface will not have the flatness of a perfect datum. You'll need to tell the machinist just how close to the datum the surface needs to be.
