I can explain what is the engineering drawing. Types of drawing, explain chapter which are important from graphics ya drawing. Orthographics and isometric views in deep level. types of lines. Also explain about projections of line, plane and solid also explain about projections of solid. also talking about the graphics and drawing of engineering. An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. 

The representation of the object in figure 2 is called an isometric drawing. This is one of a family of three-dimensional views called pictorial drawings. In an isometric drawing, the object’s vertical lines are drawn vertically, and the horizontal lines in the width and depth planes are shown at 30 degrees to the horizontal. When drawn under these guidelines, the lines parallel to these three axes are at their true (scale) lengths. Lines that are not parallel to these axes will not be of their true length.
