Life Cycle Management Model in Engineering 
For Our Purposes:
We Start Simply with Hand Sketches:
·
Learning by
mimicking and practice, each of the following collection of exercises will make
up the
first
third of Assignment 1.
EXERCISE 1: Neatly Hand Sketch (a) Each of the Five Regular Solids; (b) the sphere, torus, oblate ellipsoid, Prolate ellipsoid; (c) any other complete family of your choosing. 
Extruded Surface 
Revolved Surface 
EXERSISE 2: Create your own surface of consisting of at least 9 edges and then sketch both the extrusion of the surface and the revolution of the surface about an axis. Illustrate the process graphically as is done above. 
Solid Modeling is the
generation of geometry by the addition and subtraction of more basic solid
objects.
The
most fundamental of these basic solid objects are called primitives.
There
are five primitives:
1.
Block
2.
Cone
3.
Cylinder
4.
Sphere
5.
Wedge

EXERCISE 3: For each of the four solids shown on the right, graphically communicate their construction from primitives, mimicking the sketch shown on the left. Also indicate each mathematical relationship as shown. Carry out this exercise using hand sketching only and using one piece of paper per object.
