SOLIDS
1. Solid is a three dimensional object
2. It has three dimensions (Length, Breadth and Height /Thickness)
3. It is bounded by plane or curved surfaces
4. Atleast 2 orthographic views are required to represent a solid on
a flat surface
5. Some times additional views are necessary to describe a solid
completely

Solids can be divided into 2 main groups viz;
1. POLYHEDRA
-solids bounded by plane surfaces
such as Prisms, Pyramids etc…
2. SOLIDS OF REVOLUTION
-solids formed by revolution of linear figures
such as cylinder,cone and sphere

ORTHOGRAPHIC PROJECTION
DEFINITION
1. Method of representing the exact shape of an object in two or
more views, on planes always “at right angles to each other” by
edtending perpendiculars from the object to the planes.
2. It is universally used in engineering drawing
3. The word “ORTHOGRAPHIC” means to draw at right angles
4. Different views of an object are obtained to describe with all
dimensions
5. It is classified into 4 categories according to the orientation of
the object. But only Ist angle and IIIrd angle projections are used
in engineering drawing.
