Ruling and Measuring Tools

Ruling and measuring tools are essential in drafting, ensuring precision in technical drawings. Key tools include rulers for straight edges, protractors measure angles, while calipers and dividers ensure precise measurements. Scale rulers are vital for converting measurements to different scales. Together, these tools ensure every aspect of a draft is accurate and reliable.
