Fundamental Rules 1. Show enough dimensions so that the intended sizes and shapes can be determined without calculating or assuming any distances. 2. State each dimension clearly so that it can be interpreted in only one way. 3. • Use the same type of coordinate dimensioning system on the entire drawing. • Continuity of profile is necessary for CADD. Clearly define contour changes at the change or point of tangency. Define at least four points along an irregular profile. • Circular hole patterns may be defined with polar coordinate www.doorway.ru Size: KB.
