Pacific Arc drafting triangles are cast acrylic set squares built for accurate technical drawing. Each triangle holds true corners and straight, plain edges, so the lines you draw stay consistent from the first sheet to the last. The range covers both standard angle sets. The 45/90 degree triangle handles squares, diagonals and mitered layouts. The 30/60/90 degree triangle handles isometric work, hex layouts and stair or roof pitches. Lengths run from 4 inches for detail work up to 24 inches for full sheet layouts, and the triangles are available in clear, fluorescent orange and topaz acrylic. Orange and topaz make the tool easy to spot on a crowded desk; clear keeps the drawing fully visible underneath. These triangles are non-graduated, so there is no printed scale to distract from the drawing or wear off with use. Pair one with a T-square, parallel bar or drafting board to draw verticals and angled lines against a fixed horizontal. Architects, engineers, drafters, interior designers and industrial design students use Pacific Arc triangles for plans, elevations and sections. Outside the drafting room, the same tool works as a quilting and sewing template, a woodworking and metal layout square, a template for art and craft projects, and a geometry triangle for math and STEM classrooms. Pacific Arc has supplied drafting and measuring tools to professionals and schools for decades. Select your angle set, length and color from the options above.
