Programming with OpenSCAD

6 Dynamic Designs with if Statements

In this chapter, you’ll learn how to use if statements to create OpenSCAD designs that respond differently to a variety of conditions. This powerful programming tool gives your designs the power to choose from several options and execute only certain lines of code. As a result, you can create dynamic designs that adapt to changing circumstances. For instance, you can use if statements to reconfigure a design quickly for 3D printing.

As an example project, here you will learn to use if statements to vary the length of tick marks on a ruler to indicate inch, half-inch, and quarter-inch increments depending ...
