What do you study in machine part drawing?

The study of machine part drawing mainly involves learning to sketch machine parts and to make working and assembly drawings. This involves a study of those conventions in drawings that are widely adopted in engineering practice. – 3 –

Why is engineering drawing important in Mechanical Engineering?

Engineering drawing, is the most important aspect of mechanical engineering, as it is the fundamental need to develop the design and assembly of a machine. While the interpretation of a component in terms of sketching can be done in various methods, related to Descriptive Geometry, the three most necessary techniques of drawing/projection are:

What are the classification of drawings?

1.2 Classification of Drawings 1.2.1 Machine drawing It is pertaining to machine parts or components. It is presented through a number of orthographic views, so that the size and shape of the component is fully understood. Part drawings and assembly drawings belong to this classification.

What are assembly drawings for instruction manuals?

1.2.3.6 Assembly Drawings for instruction manuals These drawings in the form of assembly drawings, are to be used when a machine, shipped away in assembled condition, is knocked down in order to check all the parts before reassembly and installation elsewhere. These drawings have each component numbered on the job.
