MEM16006A Organise and communicate information
Interact with computing technology
you have completed this unit of competency you will have developed the
knowledge and skills to prepare the CAD environment, produce a basic
drawing, modify existing CAD drawings, produce final drawings and
perform exit and shut-down procedures.
Competency and Performance Criteria
the CAD environment
relevant manuals, instructions and operating procedures for the CAD software
are obtained in accordance with workplace procedures.
CAD package is booted up in accordance with workplace procedures.
display areas and basic parameters are set in accordance with

are prepared in accordance with AS 1100 or equivalent or in accordance with
standard operating procedures.
required, CAD drawings are reviewed with supervisor and/or other designated
staff in accordance with company procedures.
existing CAD drawings
CAD drawings are located and modified by adding, deleting or changing drawing
elements within that drawing.
files are saved in the appropriate format in accordance with standard

files are printed out using plotter or equivalent devices.
exit and shut-down procedures
and computer are shut down in accordance with workplace procedures.

| 1. The CAD System ||
of CAD software eg: 2D, 3D, surface/solid etc.
|2. Basic Operations
and shut down procedures
|3. Data Entry Methods
aids eg: grid etc
and geometric constraint modifiers
- drawing: line,
point, circle, polygon, ellipse, spline, dimension, hatch
- editing: delete,
fillet, chamfer, trim/extend, break
- transfer: move,
copy, rotate, mirror, polar and rectangular duplication
- drawing: guidelines
for efficient use (using CAD tools rather than line-by-line
- editing: modifying
an existing single view drawing of an object.
- dimensions: placing
2D drawing: completing
a single view exercise of a flat object
- plotting: producing
a hard copy (using pre-defined settings)
set of criteria
views, scenes etc
and surface finish options

may need to supply a
medium for storing their CAD files such as a CD-R or floppy disk.
- CAD program reference manuals, help, tutorials.
- Also consult websites, forums, web searches,
Wiki sites, web groups etc related to the particular CAD
drawing – Mechanical engineering drawing.

- Section 1. The CAD system:
Deals with file management and 'user interface' issues.
- Section 2. Drawing Tools:
Deals with CAD tools that produce elements such as lines, points, arcs,
dimensioning etc. and highlights the importance of positional and
geometric constraint modifiers as well as drawing aids.
- Section 3. Editing Tools:
Deals with CAD tools that work on existing elements that produce
fillets, chamfers or splitting an element into two elements etc.
- Section 4. Transformation Tools:
This tool group is similar to editing tools and include functions such
as move, copy, polar and rectangular duplication, scale etc.
- Section 5. Producing a drawing:
This section allows the student to put all the 'tools' together and
produce a CAD document Data management is covered ie. use of layers,
colour and line types and efficient construction techniques based on
the available CAD tools.
- Section 6. Modifying existing CAD drawing:
This section section 5 allows for the use of CAD tools covered in
sections 1,2,3 and 4 in making 'changes' to existing CAD documents. By
'changes' we mean either deleting existing elements and redefining them
or applying a CAD tool/command that allows changes to the element data.
- Section 7. Producing a hard copy:
This section covers the type of output devices that may be connected to
CAD systems and the actual process of readying that device for the
production of a 'hard' copy.
