the arrangements for National Qualifications. Users of
all NQ support materials, whether published by
Learning and Teaching Scotland or others, are
reminded that it is their responsibility to check that the
support materials correspond to the requirements of the
current arrangements.

INTRODUCTION
Introduction
The materials supplied consist of a series of worksheets in Adobe Acrobat
format, an Excel spreadsheet for assessment and a folder containing
‘Autodesk Inventor’ models of all the items used in the worksheets.
This course has been designed to be used in a numb er of ways. It follows the
SQA Arrangements laid down for Intermediate 1 and Intermediate 2
Technical Graphics 1 and 2. Schools can use the materials as stand -alone
courses at either level or as a bi-level course that is self-setting across both
levels.
The models contained in the ‘Inventor Models’ folder can be used in many
ways, but their primary use is in learning and teaching for the drawing ability
units. Those centres who have Inventor 11 and above can load the models and
rotate them to demonstrate the different views in each sheet. If you do not
have Inventor in your centre, a free Inventor viewer can be downloaded from
http://usa.autodesk.com/adsk/servlet/pc/index?siteID=123112&id=10535296.
This program will allow the models to be rotated and viewe d in three
dimensions. (Note: Some of the Inventor files are hidden to avoid confusion .)
The worksheets are based on content from past SQA exam papers that have
been modified to suit the course. The writers would like to thank the SQA for
allowing them to use the relevant material in this course.
Note: Only the drawing outcomes are covered within the supplied materials.
The outcomes related to knowledge and understanding are not covered and
the relative Arrangements and unit NABs should be referred to for more
information on these outcomes.

INTRODUCTION
The course
The materials supplied are divided into a number of sections that relate to the
individual outcomes as laid down in the SQA Arrangement documents. In
each section there are more than enough drawings for students to attempt.
Students do not need to attempt all drawings, although the more able student
will probably be able to do so. Within each section there are a number of
nominated drawings, which must be completed under exam conditions and
kept for inclusion in the TG1 and TG2 unit folios. Centres can decide in what
order the individual sections are completed.
Each drawing worksheet has the format shown below. The worksheets are
produced on A3 and where possible should be printed full size.

ASSESSMENT
Assessment
Included within the course materials supplied is an Excel spreadsheet , which
can be used for assessment purposes. There are several worksheet tabs within
this spreadsheet.
The first worksheet is overall assessment for the class. The worksheet is
completed using the legend 1 or 2 for each LOC, depending on the level
achieved. Columns to include grading for LOC4 are also included . However,
as previously noted, these outcomes relate to knowledge and understanding
and are not covered by this course. Relative unit NABs should be used on
these outcomes. The ‘Level achieved’ column can be completed at the
discretion of the class tutor to give an overall view of the student’s
achievement in this technical area.

must be completed under exam conditions and kept for inclusion in the unit

The second worksheet is to track homework. This is used at the discretion of
the class tutor. The worksheet operates on a ‘traffic light’ system, in which
completed homework is rated for quality and accuracy. The legend cell can be
copied and pasted to the relevant student cell. The homework checklist given
is for reference only and should be altered to suit the homework course
offered by individual departments.
Legend
Green: excellent/very
good
Amber: minor concerns
Red: major concerns.
The other worksheet tabs included are checklists for the coursework
drawings. These checklists highlight the NAB drawings in each relevant area.
They can be completed at the discretion of the class tutor either electronically
or printed on A3 paper for manual completion.
