Observation Record
Learner’s name:
Qualification:
BTEC Level 2 Diploma in Engineering
Unit number and title:
10 – Using Computer Aided Drawing Techniques in Engineering
Description of activity undertaken (please be as specific as possible)
The student started up the computer and loaded SolidWorks. The student set up an electronic
folder for their CAD work in their college user account, then created a sub-folder named
TOOLMAKERS CLAMP and saved all CAD files into that folder. The student also demonstrated
loading CAD files from that folder and saving CAD files to the same folder. The student
demonstrated closing the CAD software and shutting down the computer correctly.
The evidence for P1 & the balance of P8 was generated as students produced the drawing
template and printed drawings of the Toolmakers Clamp parts and its assembly.
Assessment criteria (to which the activity provides evidence)
P1 - Start up a CAD system, produce and save a standard drawing template and close
down CAD hardware and software in the approved manner.
P7 Set up an electronic folder for the storage and retrieval of information.
P8 Store, retrieve and print/plot seven CAD-generated or modified drawings
How the activity meets the requirements of the assessment and grading criteria (please
explain how the learner met the criteria and the qualitative aspects of their performance)
The student completed all of the above tasks to an acceptable standard which demonstrated a
good knowledge of the principles involved.
The task of starting up and shutting down the CAD software as well as the hardware was
completed each week as the student attended the lessons and worked towards and achieved
the outcomes for P2 & P3.
Each of these tasks was demonstrated by the student before this observation record was
produced.
Evidence of the students work, including completed drawings, drawing template and printing is
held as a paper copy.
