instructions.
|
2. Produce a basic drawing
| 2.1
| Basic
CAD drawings
are created and guidance is sought as required. |
| 2.2
| Drawings
are prepared in accordance with AS 1100 or equivalent or in accordance with
standard operating procedures.
|
| 2.3
| As
required, CAD drawings are reviewed with supervisor and/or other designated
staff in accordance with company procedures.
|
3. Modify
existing CAD drawings
| 3.1
| Existing
CAD drawings are located and modified by adding, deleting or changing drawing
elements within that drawing.
|
4. Produce
output
| 4.1
| Drawing
files are saved in the appropriate format in accordance with standard
operating procedures.
|
| 4.2
| Drawing
files are printed out using plotter or equivalent devices.
|
5. Perform
exit and shut-down procedures
| 5.1
| Programs
and computer are shut down in accordance with workplace procedures.
|
Glossary
Basic
parameters |
Include
layer or level, line type, line width, colour and text format etc. |
Basic
CAD drawings | Include
the following characteristics: lines, arcs, circles, polygons, ellipses,
hatching or filling of areas, text, dimensions and tangents |
Equivalent
devices | May
include inkjet printers or the like |
Knowledge and Skills
Skills |
- reading
and interpreting engineering specifications
- organising
information
- using
computers and peripherals
- using
CAD program
- preparing
simple drawings in plane orthogonal, isometric projection or equivalent
|
Knowledge |
- CAD
program capabilities and processes.
|
Delivery Plan
1. The CAD System | - classification
of CAD software eg: 2D, 3D, surface/solid etc.
- advantages
- user
interface
|
2. Basic Operations |
- start-up
and shut down procedures
- file
management
- viewing
functions
- using
on-line help
|
3. Data Entry Methods |
- rectangular
vs polar.
-
absolute
vs relative
- drawing
aids eg: grid etc
- positional
and geometric constraint modifiers
|
4.
Modelling | - 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
|
5. Techniques | - drawing: guidelines
for efficient use (using CAD tools rather than line-by-line
drawing)
- editing: modifying
an existing single view drawing of an object.
- pre-defined
templates
-
text: placing
preset text
- dimensions: placing
preset dimensions
- basic
2D drawing: completing
a single view exercise of a flat object
- plotting: producing
a hard copy (using pre-defined settings)
|
6.
Rendering techniques | - specified
set of criteria
- lights,
views, scenes etc
- materials
and surface finish options
|
7.
Completed drawing | - hard
copies
- retrieval
and use
- saving
in other formats
|

- Students
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
program.

CAD A (Superceded closest equivalent module. Correlation = high)
- 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.
