Dimensioning tips: Angles, chamfers, arcs, and fillets

- [Instructor] Most mechanical parts aren't just plain rectangular blocks. Angled surfaces and curvature are usually required for parts to be strong, light and aesthetically pleasing. In this video, we will give you some specific tips for dimensioning angles, chamfers, arcs and fillets. Angled surfaces can be dimensioned in one of two ways. In the first approach, we provide the location of the start point, as well as an angle relative to an adjacent edge. Alternatively, we can dimension the location of the start and end points without providing any angle dimension at all. Because of the trigonometry involved, the tolerance of small angles can translate into rather large variations in where the angle ultimately ends. If the location of the end of the angle is critical, consider using coordinate dimensioning. Chamfers are small-angled faces, which are used to remove a sharp corner or help components assemble more easily.…
