Unit 2 Assignment 2
Learning aim B: Develop two dimensional (2D) computer aided drawings that can be used in
engineering processes

, 2D CAD Drawings
I have drawn two components using Computer Aided Design (CAD) software: A small table and an
electrical circuit , using an array of tools and operations including commands, line and circle
drawings. To create an accurate drawing I inputted ‘x’ and ‘y’ coordinates so it is as accurate as
possible. CAD is an effective aid to creating accurate and uniform drawings to scale.
Generating an accurate orthographic projection
An orthographic projection is a method of positioning the different views of an object when
representing it in an engineering drawing.
Step 1: Drawing the initial plan - In the diagram below it shows the view of the object from directly
above. In this case the plan view consists of four circles with a diameter of 24mm, representing the
indents for the legs. There is also a large rectangle with the measurements 300mm by 200mm,
representing the workpiece prior to the edges being smoothed down. When constructing the outline of
the workpiece, instead of using the rectangle shape feature, I decided to use the line feature. Using
lines made it easier for adapting the length and rounding the corners of the workpiece. This was
because the lines can be individually managed unlike a complete rectangle which is one object so is
more difficult to manage.
The circle in the centre of the workpiece will be later created using the diameter tool in place of the
radius tool. The purpose of this decision was that the measurements made manually for the holes were
measured across the diameter of the hole so using the radius instead wouldn't be necessary.
You can use the ‘pan’ command to navigate the workpiece freely without disturbing it. It is useful for
when you want to move to a certain area of the workpiece to make adjustments. For example, when I
