Unit of Competency LMTTF3005A - Apply lofting skills to sail making
Description This unit covers the skills and knowledge required to reproduce design lines onto sailcloth using manual techniques, for the purpose of sail making.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit applies to the laying out of sailcloth on a floor and reproducing in full scale, the 'line drawings' and 'table of offsets' supplied by the sail designer onto the fabric in order to achieve a pattern with a three-dimensional outcome. Lofting is a traditional technique that does not require the use of computerised equipment.Work may involve interaction with other people in the workplace including supervisors and production personnel or sail designers. Work may be conducted in small to large scale enterprises and may involve individual and team activities. Work is performed within defined procedures under supervision of the sail designer. The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include:requirements prescribed by legislation, awards, agreements and conditions of employmentstandard operating procedureswork instructionsoral, written and visual communicationquality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section outputhousekeepingtasks related to environmental protection, waste disposal, pollution control and recyclingThis unit requires the application of skills associated with planning and organising to ensure safe and effective application of lofting skills to sail making. This unit also requires an ability to interpret sail design specifications, check the quality of outcomes, complete workplace documentation and identify production faults in own work. Self management skills are applied to ensure workplace and quality standards are achieved.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Elements of Competency Performance Criteria              
Element: Interpret lofting requirements
  • Sail design specifications are accessed and sail type is identified
  • Design lines and Table of Offsets are interpreted correctly, and sail features identified
  • Lay up specifications of sailcloth are identified
  • Amount of floor space required to lay out sailcloth is determined
  • Equipment needed for lofting is selected and set up for use
  • Steps in lofting processes are determined and sequenced for maximum productivity
       
Element: Lay out sailcloth
  • Loft floor is cleaned and checked for foreign objects
  • Sailcloth is laid out correctly using proper handling techniques, according to OHS practices
  • Sailcloth is checked for faults or inconsistencies and appropriate action taken
  • Directional and topside layout of sailcloth is checked according to fabric cutting requirements and design specifications
  • Sailcloth is braced to the loft floor using appropriate method
       
Element: Create lofted lines
  • Straight baseline is determined and created using appropriate baseline marker
  • Grid and line markings from line drawings are measured and marked onto sailcloth square to the baseline
  • Heights are measured and marked
  • Offsets are copied full-scale onto sailcloth
  • Profile lines are drawn correctly
  • Pattern is drawn from lofted lines directly onto sailcloth, with accurate allowances made for seams, joins, reinforced edges and other design features
       
Element: Complete lofting process
  • Pattern markings are checked for accuracy of three-dimensional outcome against design specifications
  • Faults in marking and inconsistencies with design specifications are identified, recorded and corrected if possible
  • Completed work is labelled, folded, packed, and loaded correctly and transferred to next area for cutting where appropriate
  • Housekeeping and required documentation is completed
       


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Demonstrates skills and knowledge to:

comply with all relevant safety requirements including safe use of tools and equipment used in handling materials, laying out and marking out

interpret and apply Design Lines and Table of Offsets defining the pattern to be marked out

interpret dimensions and other relevant specifications of components to be incorporated in pattern

apply lay out, measuring and mark out techniques

document and communicate work related information

Consistently applies skills and knowledge when:

organising work

using workplace practices

using OHS practices

recording and reporting accidents and incidents

assessing operational readiness of equipment used and work processes

recognising and adapting to cultural differences in the workplace, including modes of behaviour and interactions

completing work systematically with attention to detail without damage to goods and equipment

Context and specific resources for assessment

Assessment may occur on the job or in an appropriately simulated environment and requires access to work areas, materials and equipment, and to information on workplace practices and OHS practices.

Guidance information for assessment

This unit may be assessed independently or in combination with other relevant units.

Submission Requirements
