This document provides the details for an assignment assessing a learner's ability to modify CAD drawings. The learner is asked to update orthographic and isometric drawings of a toy train for a company called Enviroplay. The learner must modify the drawings according to provided specifications, save the drawings with new filenames, include major dimensions on a separate layer, and print copies. The learner must also justify the advantages and disadvantages of using CAD over traditional drawing methods. Upon completion, the assignment will provide evidence for several assessment criteria relating to modifying and working with CAD drawings.

Assignment title 10.5 Modifying Orthographic and Isometric Drawings
The purpose of this assignment is to:
Be able to use editing commands to modify Orthographic and Isometric Drawings
Scenario
You are working in the CAD office of Enviroplay, who supply toys for young children and make
them using sustainable materials. In the light of changes being considered, the development team
have asked you to produce the updated engineering drawings. You have been passed some
modifications to add the prototype toy train, which require you to update the current orthographic
and isometric drawings that you have already produced. The drawing of the amendment to be
made is shown below together with notes from the development team on the changes to be made.
Task 1
Update your ENVIROPLAY drawings in accordance with the modifications detailed above and save
with new filenames/drawing numbers ENVIROPLAY DRG0005 to 7 to distinguish the modified
drawings from originals. Hidden detail is needed. Major dimensions should be included for
reference using a second drawing layer. Print off A3 copies.
This provides evidence for P5 and part evidence for P8
Task 2
You are acting as a host to a student on Work Placement in the company. Make sufficient notes
that enable you to explain to the student, in some detail, the advantages and disadvantages of
using a CAD setup to produce and subsequently modify engineering drawings compared to
traditional drawing methods.
This provides evidence for D1
