A plane is a two dimensional object having length and breadth only. Its thickness is always neglected; various shapes of plane figures are considered such as square, rectangle, circle, pentagon, hexagon, etc.

A straight line is the shortest distance between two points. Projections of the ends of any line can be drawn using the principles developed for projections of points. Top views of the two end points of a line, when joined, give the top view of the line. Front views of the two end points of…

A point is simply a space location of infinitesimal size. It may represent the corner of an object, the intersection of two lines or a designated spot in space. The projection obtained on vertical plane VP is called the elevation and on horizontal plane HP, the plan. The intersection line of the vertical plane and…

The construction of plane figures such as triangle, circles, and polygons etc., used in plane geometry is called geometrical constructions. (i) A Pentagon is that which has five equal sides. (ii) A hexagon is that which has six equal sides. (iii) A heptagon is that which has seven equal sides. (iv) An octagon is that…

In Engineering Profession, it is very essential that the Engineers and Craftsmen are able to communicate their ideas and facts with each other clearly and without ambiguity. The verbal communication may be hopelessly inadequate. The written communication, on the other hand may be very inefficient, lengthy and boring to create accurate mental and physical impression…
