{"product_id":"pacific-arc-rolling-ruler","title":"Rolling Ruler","description":"\u003cp\u003eRolling rulers eliminate the constant repositioning that slows down technical drawing. This single tool functions as parallel ruler, protractor, triangle, compass, and T-square, everything you need for architectural drafting or mechanical drawing stays in one compact instrument. Built-in templates handle standard shapes without switching tools, while the rolling mechanism maintains perfect parallel alignment as you work across the page.\u003c\/p\u003e\n\u003cp\u003eThe protractor curves integrate seamlessly into the ruler's design, letting you trace accurate arcs without separate curve templates. Roll the ruler to your desired position, draw your line, then roll again; the mechanism ensures each successive line maintains exact parallel spacing. Perpendicular lines work the same way, rotate the ruler ninety degrees and the rolling action keeps everything square.\u003c\/p\u003e\n\u003cp\u003eBoth metric and imperial measurements run along the edges, covering dimensional work in either system. The included instructions detail specific techniques, though the tool's logic becomes intuitive quickly. For students learning technical drawing or professionals streamlining their toolkit, this ruler condenses multiple specialized instruments into one reliable workhorse that stays put while you draw.\u003c\/p\u003e","brand":"Pacific Arc","offers":[{"title":"12 in.","offer_id":47983028830437,"sku":"94538","price":58.44,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.texasart.com\/products\/pacific-arc-rolling-ruler","provider":"Texas Art Supply","version":"1.0","type":"link"}
