This all-in-one geometric stencil ruler is made of lightweight plastic and combines accident symbol templates, centimeter and inch scales, and multiple geometric shapes (circles, triangles, rectangles, and straight lines). It eliminates the need for separate drawing tools and improves efficiency in technical drawing and craft projects. Key benefits - All-in-one functionality: includes accident symbol templates, a measuring scale in both centimeters and inches, and multiple geometric shapes, reducing tool swaps during drawings. - Precision and clarity: clear, precise measurement marks and detailed accident templates support accurate sketches and diagrams. - Portable and durable: lightweight plastic provides easy handling and on-site usability without added bulk. - Versatile compatibility: works with standard pencils, pens, and markers; suitable for a range of drawing practices and document formats. - Clear performance indicators: designed for reliable, repeatable results in professional and educational settings. Product attributes - Material: lightweight plastic for easy transport and daily use - Scales: metric (centimeters) and imperial (inches) for versatile measurement - Shapes included: circles, triangles, rectangles, and straight lines for quick drafting - Templates: detailed accident symbol templates integrated into the ruler - Applications: geometric drawings, scaled accident scene sketches, architectural plans, and math diagrams Use scenarios - On-site accident reconstruction: quickly sketch scene layouts with accurate proportions and standardized symbols to document findings. - Educational and classroom tasks: practice geometry, create scale diagrams, or illustrate math concepts with integrated templates. - Office or workshop drafting: prepare architectural plans, technical diagrams, or craft projects requiring precise shapes and measurements. This tool provides a practical, professional, and dependable solution for precise, on-demand drafting across education, office, and field environments.
