Isometric Projection - 5

Isometric Projection - 5


Good Morning students and a warm welcome to each of you to today's class.

In the last four classes, you have leant the basics of Isometric Projection that included essentials of isometric projection, planar figures and frustums. Today we will learn about Isometric Projection of single solids.   





   Fig: 1 : Isometric Projection of a Hexagonal Prism.

Single solids could be cylinders, prisms or pyramids with triangle, square, pentagon and hexagon as face and/or base. The concepts leant in the previous classes will be used here as well. 

Recap Time: Concepts learnt previously

1. Draw the helping figure (if required) and label it appropriately. (PQRS)
2. Draw reduced or enlarged planar figures (in case of frustum).
3. Always use the Box method.
4. Draw 30-30 AXIS,
5. Draw 30-30 CROSS,
6. Finalise the Projection by darkening the visible edges of the object.
7. Indicate direction of viewing, mention all the given dimensions with proper arrowheads, and titles. 

Let's launch ourselves into practising to reach perfection



Exercise - 5 : Single solids

Instructions:

a. Show direction of viewing, show their axis and mention dimensions in all the questions.
b. Solve these questions in your drawing file
c. Please take a picture of your answers and post them in the EG Group.


Q 1. Draw an Isometric scale of length 80 mm.

Q 2. Draw the Isometric Projection of a Cylinder of diameter 40 mm kept on the HP on its curved surface and its axis perpendicular to the VP.
 
Q 3. Draw the Isometric Projection of a pentagonal pyramid of base edge 30 mm and height 70 mm kept on the HP with one of its base edges perpendicular to the VP.
