Pacific Arc Drafting Triangle 20 in 30/60/90 - Precise Angles

Our review of the Pacific Arc Drafting Triangle finds it to be a straightforward, reliable tool for anyone who needs precise geometric guides. Designed with architects, engineers, drafters and quilters in mind, this 20 in triangle delivers a stable, plain edge and clear visibility thanks to its fluorescent orange, pure acrylic construction. The single biggest reason to buy is accuracy: the non-graduated 20 in length and true 30/60/90 corners give repeatable, clean angles for layouts, templates and technical drawing tasks.

Key Features

• Professional drafting design: Built for architects and engineers, the triangle gives accurate lines and precise angles that suit technical drawing work.
• Pure acrylic construction: The.080 in thick acrylic provides a rigid, flat surface that resists bending during regular use.
• Fluorescent orange color: High-visibility coloring helps the tool stay easy to find on a crowded work surface or in a sewing studio.
• Plain, strong edge: The smooth, non-graduated edge is intended for long-lasting use and produces clean ink or pencil lines.
• Versatile 30/60/90 corners: The fixed angles cover the most common needs for drafting, quilting templates, and layout work.
• Accurate 20 in length: A full 20 in hypotenuse gives a large working surface for bigger sheets and pattern work.

Who It's For

The Pacific Arc Drafting Triangle is best for professionals and students who routinely draw or measure on larger sheets: architects, engineers, technical drafters, and advanced quilting hobbyists will appreciate the true 30/60/90 angles and the 20 in size. Its rigid.080 in acrylic construction holds shape well for precise line work.

Those who need metric graduations, a ruler with marked measurements, or a smaller portable triangle should look elsewhere, since this is a non-graduated, single-piece triangle focused on angle accuracy rather than measurement markings or compact storage.

Pros & Cons

Pros

• Accurate 30/60/90 corners that make consistent angle layout quick and reliable.
• Sturdy.080 in pure acrylic construction provides a rigid, durable tool for repeated use.
• Fluorescent orange color improves visibility on busy worktables and reduces misplacement.

Cons

• Non-graduated edge means it does not replace a marked ruler for precise linear measurements.
