Building a LEGO Brick

In this section, we’ll walk through a complex modeling project that uses parameters, modules, and for loops in a single design. You’ll design a LEGO brick shape that has two studs in one direction and any number of studs in the other direction. Studs are the small bumps on the top of a LEGO brick that fit into other LEGO bricks to hold them together. Figure 5-3 shows a LEGO brick with two rows and four studs per row.

Before coding a complicated design like this, sketching a few hand-drawn versions of your shape can help you gain a firm understanding of the dimensions and patterns that exist within the shape (Figure 5-4).
