Unit of competency
Modification History
Release 1. Supersedes and is equivalent to MEM09202A Produce freehand sketches.
Application
This unit of competency defines the skills and knowledge required to complete freehand sketches to illustrate or communicate information to be used in engineering drafting applications. It includes the use of standard drawing conventions and techniques to represent the subject in appropriate proportion and view. Sketches can be used as part of the drafting process to illustrate or communicate information about design, worksite, layout plan or construction features and the unit includes the ability to apply standard drawing conventions to sketching 2D orthogonal and pictorial freehand drawings and sectional views.
This unit is suitable for those working within a computer-aided design (CAD) or drafting work environment.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Competency Field
Drawing, drafting and design

Assessment requirements
Modification History
Release 1. Supersedes and is equivalent to MEM09202A Produce freehand sketches.
Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:
- following work instructions, standard operating procedures (SOPs) and safe work practices
- determining the job scope and sketch requirements through consultation with relevant personnel
- producing an initial simple freehand sketch on at least two occasions using standard drawing conventions and identifying and labelling to confirm currency and purpose
- confirming sketch is a proportional presentation of subject with relevant personnel
- producing freehand orthogonal sketches and sectional views to communicate or illustrate subject for further drafting work on at least two occasions
