So, I am a fan of Lego, who isn't? One of my favorite things to do while using Maya was to model Lego pieces as I built a new Lego project. I want to do that same sort of thing in Blender, but I don't know how to do precise modeling.
For example, if you have a Lego piece that measures 47.75mm (x) x 15.75mm (y) x 3.15mm (z), once I add a new cube primitive and want to use these measurements, how does one go about doing that? I haven't been able to figure this out yet.
