Application
This unit of competency defines the skills and knowledge required to produce and interpret lines plan drawings manually or using computer-aided design (CAD) equipment complying with industry standards.
It applies to drawing and lofting principles used to produce lines plan drawings and loftings and common applications of this unit are in marine vessel construction.
In a marine setting, tasks may relate to drawings for hull designs, section development, including curved and raking transom, conical development and camber development methods.
Where a CAD system is used for basic drawing unit MEM09003 Prepare basic engineering drawing should also be selected.
Where more extensive CAD system is used for design unit MEM09009 Create 2-D drawings using computer-aided design system should be selected.
Where straightforward take-offs from lofted drawings, or where transfer of lines to lofting floor or other surface is required to be carried out, unit MEM12007 Mark off/out structural fabrications and shapes should be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
What You'll Learn
1. Determine job requirements
- 1.1 Follow standard operating procedures (SOPs)
- 1.2 Comply with work health and safety (WHS) requirements at all times
- 1.3 Identify design requirements from specifications, job sheets or associated work instructions
2. Apply drawing procedures
- 2.1 Determine and outline lines drawing procedures and identify data requirements
- 2.2 Set up appropriate drawing equipment to suit requirements
- 2.3 Apply drawing procedures to suit specified drawing
- 2.4 Record any alterations to offset measurements, where applicable
- 2.5 Ensure drawings are consistent with operation procedures and industry requirements
3. Submit lines plan drawings
- 3.1 Submit completed drawings in accordance with industry standards
- 3.2 Supply altered offset measurements and relevant drawing information, where applicable
Assessment Requirements
Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:
following work instructions, standard operating procedures (SOPs) and safe work practices
determining drawing requirements
applying drafting procedures to produce curved 3-D shapes using appropriate drawing equipment ensuring they are consistent with operation procedures and industry requirements
undertaking numerical operations, geometry, calculations and formula associated with interpreting and producing curved 3-D shapes
submitting completed drawings to applicable personnel and supplying altered offset measurements and all relevant information.
Knowledge Evidence
Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:
safe work practices and procedures
vessel design characteristics, including performance, stability and construction methods
data requirements for producing lines plan drawings
numerical operations, geometry, calculations and formulae
spatial concepts
drawing techniques and procedures and use of equipment
industry standards, terminology and symbols applying to lines plan drawings.
Assessment Conditions
Assessors must:
have vocational competency in interpreting and producing curved 3-D shapes at least to the level being assessed with relevant industry knowledge and experience
satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires
Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Foundation Skills
