uniformly scaling it. Your setup should look like the following screenshot:
So we're going to grab the builder brush's edges and move them around unil the brush is big
enough, but how do we tell how big it is? There's nothing that tells us the cube's size directly.
We can use the measure tool to drag in a 2D view and measure distances. Just click-and-drag
with the middle mouse buton.
