The Alvin Graduated Beam Compass handles arcs up to 48 inches in diameter, bringing professional-grade capability to architectural drawings, engineering layouts, and large-format design work. Spring-loaded thumbwheels on each slide assembly enable smooth, incremental adjustments, critical when positioning components for accurate radii. The graduated beam provides clear measurement reference as you work.\u003c\/p\u003e\n\u003cp\u003eGerman engineering shows in the construction: heavy-duty materials resist the wear and corrosion that come from studio environments, maintaining smooth operation through years of use. Three interchangeable legs adapt the compass to different tasks, ruling pen for ink work, pencil for layout and development drawings, divider points for transferring measurements and stepping off dimensions. Whether you're developing construction documents, creating technical illustrations, or teaching geometry principles, these tools deliver the precision large-scale work demands.\u003c\/p\u003e\n\u003cp\u003eThe rigid plastic case protects components during transport and keeps everything organized between projects. Students gain exposure to professional-quality instruments; practicing architects and engineers get reliable performance for presentation drawings and site plans.\u003c\/p\u003e","brand":"Alvin","offers":[{"title":"beam compass","offer_id":47983047016677,"sku":"16096","price":69.82,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.texasart.mom\/products\/alvin-graduated-beam-compass","provider":"Texas Art Supply","version":"1.0","type":"link"}
