CPPBDN4006
Import and transpose information from external sources into digital building design drawings


Application

This unit of competency specifies the outcomes required to import drawing files and transpose information from drawings prepared by external surveyors, engineers and construction consultants into existing digital building design drawings for residential, commercial and industrial buildings as defined by the Building Code of Australia (BCA), using building information modelling (BIM)-capable building design software.

It also covers understanding and applying functions and options of drawing software for different methods of importing files and for managing elements in imported drawings.

The unit supports the work of drafters who assist and work under the supervision and instruction of architects and building designers and who check drawings and reports for accuracy and compliance with relevant legislation, regulations, codes and standards before importing or transposing into existing drawings; and who then check the integrity and accuracy of the completed drawings.

Licensing, legislative, regulatory or certification requirements apply to building design drafting in some states. Relevant state and territory regulatory authorities should be consulted to confirm those requirements.


Elements and 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.

1.

Amended drawings are requested, noted details of amendments required are provided, and amended drawings are obtained from relevant engineers or consultants according to workplace requirements.

2.

Import drawings from external sources into digital building design files.

2.1.

Compatibility of digital drawings from external sources for importing into digital building design files is determined and confirmed with architect or building designer.

2.2.

Building design software and work instructions relating to the importing of drawings from external sources are interpreted to determine options to be applied for different building design projects.

2.3.

Method for importing drawings is applied according to work instructions.

2.4.

Import options are applied to incoming files according to work instructions.

2.5.

Files depicting materials and scenery are imported to enhance presentation and conceptual drawings, as required.

2.6.

Digital building design files are re-named and saved according to workplace requirements.

2.7.

Files are checked for integrity, submitted to architect or building designer for approval, and amendments made as directed.

3.

Transpose information from externally-sourced drawings into digital building design files.

3.1.

Work instructions for transposing information from externally-sourced drawings into digital building design files are interpreted and confirmed with architect or building designer.

3.2.

Information is added to drawings according to work instructions and checked for accuracy and completeness of transposition according to workplace requirements.

3.3.

Details of externally-sourced documents are added to the list of supporting documents in the drawing set.

3.4.

Digital building design files are re-named and saved according to workplace requirements.

3.5.

Files are checked for integrity, submitted to architect or building designer for approval, and amendments made as directed.
