E-Portfolio: Working Drawing
A working drawing also known as an orthographic
projection is a method that allows someone to represent
a three-dimensional object on a two-dimensional piece of
paper. By drawing the object for a various angles, the
artist is able to show how the object looks in the real
world. The process is called orthographic projection. A
working drawing should be set out in a certain way
(standardised) that all manufacturers across the UK can
use to make the product in real life from your drawings.

In your design portfolio, you should show that you have:
 

used an appropriate template

used a basic range of CAD drawing and editing commands

used the correct tools to produce the correct geometry

used the correct tools to manipulate views on screen

used a range of further CAD commands including coordinates, features and modification techniques

used dimensioning and hatching techniques

produced a drawing that meets the expected standard (BS8888) saved the drawing in the correct format.

Orthographic drawings usually consist of a front view,

a side view and a plan view, but more views may be

shown for complex objects with lots of detail.

A drawing board and parallel motion or T-square is used

to project one view from another. Orthographic drawing

may be done using first angle projection or third angle

Projection. An orthographic projection of the shape on

the right is shown below.

HOW TO LAYOUT YOUR A WORKING DRAWING

Using CAD in your design portfolio and developing your in CAD allows you to produce orthographic drawings very quickly. This allows third parties to manufacture them provided you lay them out using the standardised method. Information found on a working drawing / orthographic drawing:



Below are two step by step guides to produce an orthographic drawing for a product. Adapt them to to suit your own designs. Click on the owl button to bring up the tutorials and follow step by step.

This page is entirely up to you how you how you present it and can be a mixture of some of the details below that you are going to explore and your own ideas. You need to present the following:


You can also present the following:


Sectional and assembly drawings

Some products may need a section drawing to give extra structural information, or an assembly drawing to show how parts fit together.


As already explained orthographic drawings usually consist of a front view, a side view and a plan view. This allows third parties to manufacture them, as shown in the two videos below.
