Tools for Engineering Design 2
CAD Assessment 2022
In the CAD exercise, you will produce a set of 2D CAD drawings based on the Design, Build, Redesign project.
This is a self-learning assessment exercise in which you will use an industry standard CAD package, AutoCAD.
What type of CAD drawings should you produce?
CAD (computer aided design) drawings are widely used to communicate details of a design, particularly when
it is ready to be constructed. CAD is a very powerful tool, and capable of producing extremely complex 3D
drawings and visualisations. CAD also interfaces with other design tools such as structural analysis software
(e.g. finite elements analysis) or building information modelling (BIM).
For TED2, however, are only focusing upon simple 2D line drawings (plan, sections, elevations, connections
etc.), with black and coloured lines on white paper, similar to those in the self-assessment drawings. 3D views
and rendering are not wanted: 2D line drawings are usually the clearest way of precisely communicating the
details of a design.
What should the drawings show?
Prepare a set of 2D technical drawings that show your group’s Week 4 crane design, operation and
construction method. These will be assessed on the quality and clarity of your drawings and communication,
not upon the quality of your design. The drawings must communicate every aspect of the structure that your
group designed. You can enhance and edit your design and communication based on the formative feedback
from Week 5
Some guidance on good technical drawings
• Before starting, think carefully about drawing layout and how best to completely communicate your
design. Be critical about your group’s original drawings; start afresh and do not just reproduce the
original drawings.
• The teach-yourself-CAD material should have shown you that CAD is a precise tool for scale drawings,
in which everything is drawn accurately and clearly. We are looking for professional and complete 2D
CAD drawings.
• Your drawings should use A3 paper. Make sure they are legible and well-proportioned once printed at
A3. For example, you might not realise that your font size is very small until you see it printed out.
• You can use coloured lines for your drawings, but the drawings need to be legible when printed in
black and white, with different line weights and styles used to ensure information is clear.
• Drawings should not contain long tracts of text. For example, the construction method of the
structure should be illustrated, not written as textual instructions.
• Include a title block and border, similar to the one in the self-assessment drawings.
Submission and Assessment
The CAD exercise requires an individual submission and should not be carried out as a group. It should be
submitted at the end of the semester (Friday, 1pm, Week 11 –8th of April 2022) via learn. Table 1 overleaf has
a break down of how this piece will be marked.
1. Print your CAD drawings to a .pdf file (A3 paper size) and include with them the original set of
drawings from Week 4. Submit as a single .pdf file.
• There are a number of ways to merge pdfs into a single file; e.g. http://merge.smallpdf.com,
or Mac users can use the built in preview.app; see the app help file
2. Also submit the AutoCAD .dwg file separately. Again this should be a single file.

Both files are submitted correctly. (100%)
Crane design
communication (25%)
Only one or two views of the crane, drawing in a
simple style, that hinders communication of
crane concept. Lacking evidence of skills of using
line weights, dimensions, colours, and hatching.
An excellent set of crane design drawings that
only need minor tweaks to show crane fully.
Evidence of a good amount of skill of using line
weights, dimensions, colours, and hatching
Operation and
construction process
drawings (40%)
Operation and construction process has both text
and images, but is too reliant on the text to
communicate what the process is. Lacking
evidence of skills of using line weights,
dimensions, colours, and hatching.
An excellent set of operation and construction
process drawings that only need minor tweaks
to show crane fully. Evidence of a good
amount of skill of using line weights,
dimensions, colours, and hatching.
Appropriate layout
and content of pages
(25%)
Some attempt to place images into a formal
format has been made but is not consistent
between pages. (e.g. pages flip from landscape to
portrait, it is plain white page with no boarder or
title block)
Goes beyond the basic layout provided and is
set out in a way that means all the information
is easy to find (e.g. consistent location of key),
but could do with several minor tweaks to be
able to be used by others.
