Study Notes
Drafting Tools
- Drafting tables feature a slanted adjustable surface, enhancing ergonomics during drawing tasks.
- T-squares assist in creating parallel horizontal lines, crucial for accurate drafting.
- Triangles are essential for accurately drawing angles of 90°, 60°, 45°, and 30°.
- Triangular scales, or architect's scales, have a three-lobed cross-section with six measurement scales, facilitating precise scale drawings like blueprints and maps.
- Compasses are used to draw large arcs and circles, providing flexibility in design.
- Divider tools measure equal divisions of lines or spaces, useful for trial and error in drafting.
Measurement and Angles
- Protractors are semicircular instruments utilized for measuring and laying out angles and arcs.
- French curves guide the drawing of irregular curved lines, aiding in more complex designs.
Erasing and Corrections
- Erasing shields protect surrounding areas when clearing smudges or lines, constructed from thin metal with irregular holes.
- Pencils are crafted from graphite within wooden or plastic casings, pivotal for writing and drawing.
Types of Pencils
- Wooden pencils are traditional tools for sketching, while mechanical pencils offer precision.
- B-grade pencils contain more graphite, producing darker lines but can be smudgier.
- H-grade pencils have higher clay content, yielding lighter lines with reduced smudging.
Drafting Media
- Drafting media encompasses the papers and films used for drawing; types include tracing and vellum.
- Sketching can occur on various paper sizes and types, while architectural drafting adheres to standard sizes.
Tracing Paper
- Tracing paper, or TRACE, is a medium-grade transparent paper suited for developing initial layouts and concepts.
Drafting Vellum
- Drafting vellum, or tracing vellum, is high-grade transparent paper that allows easy erasure of pencil lines, facilitating reproductions.
Additional Tools
- Masking tape secures drawing papers to drafting tables or boards, preventing movement during work.
- Erasers come in soft and hard varieties; soft erasers remove smudges, whereas hard erasers correct detailed errors.
- Rulers are fundamental in engineering and construction for measuring distances and drawing straight lines.
