7.1 Basic Drafting Tools and Techniques

Drafting tools are the foundation of creating precise technical drawings. From T-squares to compasses, each instrument plays a crucial role in producing accurate and professional-looking designs for theater and film sets.

Mastering drafting techniques is essential for communicating design ideas effectively. Line weights, text standards, and drawing conventions help convey depth, importance, and specific information, ensuring clear interpretation of set designs by production teams.

1 of 3

• T-square serves as a guide for drawing horizontal lines and aligning other tools
• Triangles come in 30-60-90 and 45-45-90 degree angles, used for creating vertical and angled lines
• Scale ruler features multiple scales for accurate measurements and proportional drawing
• Drafting pencils range from 6H (hardest) to 6B (softest), allowing for varied line weights and textures

Precision and Correction Tools

• Eraser shield protects surrounding areas while erasing specific lines or details
• Compass creates precise circles and arcs of varying sizes
• Drafting tape secures paper to the drawing surface without damaging it
• Drafting board provides a smooth, stable surface for creating technical drawings

Drafting Techniques

Line Weights and Types

• Line weights vary thickness to convey depth, importance, and visibility of elements
  • Thick lines represent foreground or cut elements
  • Medium lines show visible edges and contours
  • Thin lines indicate hidden details or construction lines
• Different line types convey specific information
  • Solid lines for visible edges
  • Dashed lines for hidden features
  • Center lines for symmetry and alignment

Text and Symbol Standards

• Lettering styles maintain consistency and legibility across drawings
  • Block lettering for titles and headings
  • Architectural lettering for notes and dimensions
• Drafting symbols standardize representation of common elements
  • Door and window symbols
  • Electrical and plumbing symbols
  • Material hatch patterns (brick, concrete, wood)

Drawing Conventions and Layout

• Title blocks contain essential project information (name, date, scale)
• Proper sheet orientation and layout maximize drawing space
• Dimensioning techniques accurately convey measurements
  • Extension lines
  • Dimension lines
  • Arrowheads or tick marks
