When 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. 


Elements of Competency and Performance Criteria

1. Prepare the CAD     environment


All relevant manuals, instructions and operating procedures for the CAD software are obtained in accordance with workplace procedures.


The CAD package is booted up in accordance with workplace procedures.



Screen display areas and basic parameters are set in accordance with instructions.

2. Produce a basic drawing


Basic CAD drawings are created and guidance is sought as required.


Drawings are prepared in accordance with AS 1100 or equivalent or in accordance with standard operating procedures.


As required, CAD drawings are reviewed with supervisor and/or other designated staff in accordance with company procedures.

3. Modify existing CAD drawings


Existing CAD drawings are located and modified by adding, deleting or changing drawing elements within that drawing.

4. Produce output


Drawing files are saved in the appropriate format in accordance with standard operating procedures.


Drawing files are printed out using plotter or equivalent devices.

5. Perform exit and shut-down  procedures


Programs and computer are shut down in accordance with workplace procedures.


Basic parameters Include layer or level, line type, line width, colour and text format etc.
Basic CAD drawingsInclude the following characteristics: lines, arcs, circles, polygons, ellipses, hatching or filling of areas, text, dimensions and tangents
Equivalent devicesMay include inkjet printers or the like

Knowledge and Skills 
  1.  reading and interpreting engineering specifications
  2. organising information
  3. using computers and peripherals
  4. using CAD program
  5. preparing simple drawings in plane orthogonal, isometric projection or equivalent
