Notes

Elements and Performance Criteria

1 Plan and prepare for drawing requirements.

1.3 Determine method of recording feature details in accordance with nature of the feature, location and accessibility.
1.4 Determine and apply method and system of recording identification, location and dimensional information in accordance with requested drawing requirements.
1.5 Identify, list and use equipment and instruments in accordance with recording task requirements.

2 Organise information for drawing preparation.

2.1 Gather information to identify and group all recorded details associated with each area or section of the building or structure.
2.2 Determine size of the drawing and scale to be used in accordance with dimensions of building, structure or section.
2.3 Identify and locate sketches, tracings or photographs of recorded features with other recorded information related to feature work.
2.4 Identify and locate sketches, tracings or photographs of recorded features with other recorded information related to feature work.

3 Draw or develop orthographic description.
