Elements

Performance Criteria

Elements describe the essential outcomes

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section

1. Prepare for the job

1.1 CAD project objectives and job order are identified and confirmed according to workplace procedures

1.2 CAD requirements and processes are determined based on consideration of project and identified parameters

1.3 Required computer software is selected and installed if required according to workplace procedures

1.4 Files of digitised information relevant to the project are retrieved and converted if required

2. Gather measurements

2.1 Measurements of components, sub-assemblies and products are identified and recorded

2.2 Calculations of required dimensions and other drafting details based on measurements are made

2.3Critical information relevant to the CAD project is identified

3. Prepare drawings

3.1 Critical dimensions and data for the required drawings are established

3.2 Preliminary sketches are prepared and reviewed with appropriate personnel

3.3 CAD package is accessed using the necessary commands according to project objectives, operating instructions and workplace procedures

3.4 2D and 3D computer graphics systems are used to meet project objectives and specifications

4. Check and save drawing files

4.1 Drawings are checked against project objectives and specifications

4.2 CAD data files are stored according to workplace procedures and archiving requirements

5. Plot drawings

5.1 Computer hardware is activated to scan, print or plot as required

5.2 Retrieved information is plotted according to software instructions and task requirements

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Critical information must include:

drafting standards

measurements of components and sub-assemblies

system accuracy

workplace-accepted tolerances.
