In this video, I finally figure out how the Ruler Tool works in Tinkercad. At first glance, it might seem intimidating—but it’s actually a powerful tool for placing objects and holes exactly where you want them. While the Align and Workplane tools are great for snapping things to centers or edges, the Ruler Tool gives you the kind of precision control those tools just don’t offer. I break down how the Ruler Tool works, show where it really shines, and explain how it complements the other tools to give you full control over your designs.
