Introduction to Drawing

Introduction to Engineering Drawing and its Significance

• Drawing is an art of representing objects or forms on a flat surface or a canvas chiefly by means of lines, using wide variety of tools and techniques.

• Engineering Drawing is a graphical way to convey an unambiguous and accurate description necessary for engineered items.

• Engineering drawing is a two dimensional representation of three dimensional objects.

• In general, it provides necessary information about the shape, size, surface quality, material, manufacturing process, etc., of the object.

• It is the graphic language from which a trained person can visualize objects.

• The purpose of engineering drawing is to provide exact geometrical configuration for the construction or analysis of machines, structures or systems.

Drawing conveys the following critical information about the

(i) Geometry of the object

(ii) Dimensions of the object

(iii) Tolerances of the Object

(iv) Material of the object

(v) Quality of the object

Applications :

The subject in general is designed to impart the following skills.

• Ability to read and prepare engineering drawings.

• Ability to make free - hand sketching of objects

• Power to imagine, analyze and communicate

• Capacity to understand other subjects

Some Examples of the Drawing are given below:

 

Works can be completed without presence of an Engineer once his ideas are communicated in the form of drawing .
