Necessity of dimensioning, Types of dimensioning (chain, parallel and progressive

dimensioning) size and location dimensioning Methods of placing dimensioning

(Aligned and unidirectional system), use of leader lines. General principles of

dimensioning, Dimensioning of overall sizes, circles, thread holes, chamfered

surfaces, angles, tapered surface holes equally spaced on PCD, counter sunk hole

counter bored holes, cylindrical parts, narrow space and gaps, radii, curves and

arches
