To make the promised rounded box, take the hull() over four cylinders, one located at each of four edges. Hull() takes any number of objects and builds their convex hull the action is like wrapping cling film tightly around the shapes and solidifying the result. If you’ve never really understood hull() before, this is a great place to start. I’ve even seen people make rounding tools and difference them out of the model.įor me, the most intuitive method is to place the four cylinders that would be the box’s round edges, and connect them all together with hull(). A simple declarative programming language defines Constructive Solid Geometry (CSG) operations like unions, intersections, differences, which can be parameterized with loops and variables.

It’s essentially a CAD software for programmers with a minimalist UI. Another method, that renders a lot faster, is to draw a 2D square, offset() it with rounded edges, and extrude this upwards. OpenSCAD is a popular open-source design tool for 3D printing afficionados (and others).
One is to draw a 3D box and minkowski() around it with an appropriate cylinder. There are multiple ways to make a rounded box. If you use OpenSCAD and your creations end up with hard edges, or you spend too much time figuring out angles, or if you just want to experience another way to get the job done, read on! And with a little ingenuity, hull() can provide a nearly complete modelling strategy all on its own. Hull() solves a number of newbie problems: making things round and connecting things together.
Hull() does just what it says on the can - creates a convex hull around the objects that are passed to it as children - but that turns out to be invaluable. What’s your favorite OpenSCAD command? Perhaps it’s intersection() or difference()? Or are you a polygon() and extrude() modeler? For me, the most useful, and maybe most often overlooked, function is hull().
