MEM30001A UNIT INFORMATION (CIDO)

Elements of Competency and Performance Criteria

1. Identify drawing requirements

1.1 

All relevant job requirements and design specifications are obtained in accordance with workplace procedures.

1.2

Drawing requirements and specifications are identified and interpreted.

2. Prepare assembly, layout and general drawings in accordance with instructions

2.1
 

Drawings are prepared in plane orthogonal, isometric projection or equivalent including sections to Australian Standard 1100, as required.

2.2
 

Problems are resolved in consultation with a supervisor.

3. Draw sections through simple engineering components as required for clarity

3.1
 

Sections are drawn through an engineering component incorporating correct use of cutting plane(s) symbols and conventions.

4. Select physical dimensions from manufacturer handbooks

4.1
 

Where required, components and/or materials are selected from supplier/manufacturer catalogues using predetermined design specifications.

5. Prepare engineering parts list

5.1
 

An engineering parts list is produced in accordance with workplace procedures.

6. Issue or file completed drawing/parts list

6.1
 

Approved drawings and/or parts lists are stored, catalogued and issued in accordance with standard operating procedures.

 Glossary
