Multipurpose Geometric Ruler Stencil

This multifunctional drafting tool combines a precision dual-scale ruler (centimetres and inches), accident-scene symbol templates, and standard geometric shapes including circles, triangles, rectangles, and straight-line guides. It is constructed from durable, lightweight plastic for repeated field and classroom use. Dimensions: approximately 30 cm long × 10 cm wide; weight: under 80 g. Designed for clarity and accuracy, all markings are laser-etched or deeply embossed for long-term legibility. The integrated accident-scene symbols — such as vehicle outlines, skid marks, directional arrows, and pedestrian icons — align seamlessly with the built-in metric and imperial scales, enabling rapid, proportionally correct scene documentation. Core geometric shapes support angle measurement, symmetry exercises, and scaled diagramming without requiring additional tools. Use it in secondary school mathematics lessons to demonstrate scale drawing and spatial reasoning; during roadside or forensic investigations to produce admissible, measurement-backed scene sketches; or in engineering and architectural workflows where quick hand-drafted concept sketches must maintain dimensional integrity.
