If you swap this to “false” and again press F5, you will see the origin point of the cube object change to one of the corners. The “true” defines that we want the cube’s origin point to be the center of the cube structure. You can probably guess that the “5” inside the brackets refers to 5mm as the size of the edges of our cube. To create a preview of your code, press F5. Once you have typed in the code, press “enter” and you will move to the next line in the code window, however, you won’t see your cube. Most lines of code in OpenSCAD will require this semi-colon. Note that this line of code has a semicolon at the end. There’s a code input area on the left and a preview window where your model appears on the right. Look at some of the examples to see OpenSCAD capabilities, although they tend to be quite complex. Once installed, launch the software and you’ll see a window asking if you want to create a new project or select an example from the menu on the right. Head to and download the current version of OpenSCAD. OpenSCAD has a large, friendly community of users and lots of helpful online tutorials. It takes time to become an expert user, but never fear. ![]() So, if you tinker with code, OpenSCAD is quite simple. As with any Computer Aided Design (CAD) environment, you will find that you repeatedly have to type in dimensions, coordinates, and more. ![]() This might sound complex, but it makes sense. This is excellent software that allows you to create 3D designs by typing code. Learn the basics of OpenSCAD 3D in this fun labĪ while back in our article about free and open-source 3D modeling, we mentioned alternatives to Blender including OpenSCAD.
