Elements and Performance Criteria

1. Set up and manage files for digital 3-D models of small-scale building design projects.
   • Files are created, named, saved and retrieved according to project and workplace requirements.
   • Digital two-dimensional (2-D) drawing files are imported as required using suitable file transfer protocols.
   • Files are exported and transferred for client and consultant use in required formats using suitable file transfer protocols.
2. Create digital 3-D models of building designs.
   • Sources of customised architectural objects for digital 3D models are identified and accessed.
   • -D modelling functions of design software are operated to create -D model and additional objects according to project and workplace requirements.
   • Architectural objects are applied to 3-D models according to project and workplace requirements.
3. Produce digital 3-D model presentation.
   • -D models are manipulated to create a range of views according to project and workplace requirements.
   • Dimensions and notations are applied to views as required.
   • -D models are checked for accuracy, completeness and quality according to workplace procedures.
   • Presentation styles and display controls are selected and applied according to project and workplace requirements.
4. Present digital 3-D models to clients.
   • -D models are presented and explained to client to ensure client understanding of designs, according to workplace procedures.
   • Client feedback is encouraged and incorporated into models.
   • Files for finalised 3-D models are saved and processed according to project and workplace requirements.

Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit.

The person must also produce three-dimensional (3-D) models of building designs for three different projects, consisting of:

one Class 1 residential building of three storeys

one residential extension of at least 50 square metres

one of the following non-residential projects which must be of a maximum area of 2000 square metres:

incorporating Classes 2, 5, 6 and 7a

incorporating Classes 3 and 9c

incorporating Classes 7b and 8.

In doing the above, the person must:

meet client expectations and workplace requirements

present digital 3-D models to clients and:

explain design using terms suitable for clients’ understanding

encourage and respond to questions and feedback.
