Elements and Performance Criteria

1. Confirm project and drawing requirements
   • Confirm project requirements for computer-aided design (CAD) drawings
   • Identify drawing requirements, purpose and scope and confirm with relevant project personnel
2. Create drawing template files to meet standard drawing requirements
   • Set up basic drawing environment
   • Create layering strategy as required
   • Create arboricultural and architectural library of standard detail and components
   • Create text and dimension styles
   • Create line types of different thicknesses to provide visual differentiation of plan elements
   • Create hatch patterns and types
   • Set up title blocks for different drawing sizes
   • Set up reference schedules as required
3. Create 2-D drawings
   • Use 2-D CAD software programs and functions to produce different types of 2-D drawings using appropriate layers as required
   • Import digital text and drawing files from other software applications into 2-D CAD drawings
   • Scan and save hard copy documents as correct file types to import into 2-D CAD drawings
4. Edit, measure and inspect drawing components
   • Delete or purge elements that are not required from drawings
   • Add notations to drawings as required
   • Add dimensions and scales to drawings as required
   • Use editing commands to modify drawing elements and text
   • Plot trees with precision
   • Differentiate visually trees to be retained, removed and transplanted
   • Calculate areas of tree protection zones (TPZ), encroachments and distances
   • Undertake quality control check of drawing
5. Print CAD drawings
   • Set page layout with appropriate scale and lineweights for the drawing file to suit printing requirements
   • Set print parameters for the printer
   • Print drawings on the correct media
6. Save and back up files
   • Create suitable file directories for the drawing project
   • Save drawing files for later retrieval and back up to specified drives or directories
7. Export files
   • Create drawing files and send to external personnel for use in different software applications
   • Create portable document format (PDF) files for relevant personnel to view completed drawings without using CAD software packages
