1ĭespite being actively developed, broadly used and powerful 2 there are many shortcomings which make it difficult or sometimes impossible to use outside of 3D printing. It’s popular within the 3D-printing community due to its ability to produce STL files. As it’s script-based, it’s fantastic for parametric design and the files can be version controlled just like a software project. Portions of this tutorial also appear by the same author in her "Tutorial Tuesday" column at the Shapeways blog.OpenSCAD is an open-source CSG based script-only CAD package. The result should be a translated sphere of radius 10mm. For example, to un-comment the code snippet below, remove the start and end codes and then compile with “F5”. The second way that comments can appear in OpenSCAD is between the start-comment code “/*” and the end-comment code “*/”. If you want to make the sphere go away again, then just put the comment symbol back in. The result should be a sphere of radius 10mm. For example, to see what the piece of code below does in OpenSCAD, you would erase the comment symbol “//” at the start of the line in the OpenSCAD Tutorial Code file, and then compile the code with “F5”. So how do you un-comment something? Comments in OpenSCAD can appear two different ways: First, anything preceded by the double-slash “//” will be ignored. More precisly, to use this tutorial, try un-commenting some code to make it active, then press “F5” (or “Function-F5” on some smaller or laptop keyboards) to see the result of the code in the graphics window. “Commented” code is ignored by the compiler, so only uncommented code will be run and displayed. The way to use this tutorial code is to download it, open it in OpenSCAD, and then start un-commenting pieces of code to see what they do. If you haven’t done that yet, then try out this OpenSCAD Tutorial Code written by former JMU 3SPACE student Tony Mannino. Tony’s tutorial code will help you learn how to create basic OpenSCAD objects, how to modify those basic objects, and even how to combine objects and create code loops. Watching videos and reading tutorials is great, but to really learn to code you have to get in there and type it yourself. This playlist is how some of us at 3SPACE initially learned about OpenSCAD, and the videos are very clear, simple, and easy to follow. If you like learning by video then you should also check out Patrick Conner’s video playlist of OpenSCAD tutorials. Or, get started in less than 10 minutes by watching and playing along with the video PolyBowls – A simple OpenSCAD code walkthrough. For extensive documentation and examples, see the Thingiverse OpenSCAD Jumpstart page and OpenSCAD discussion group. Step 2. Jump right in with tutorials and videosįor a quick start, check out the Hello OpenSCAD one-page starter document with OpenSCAD sample files. The fastest way to find reference information is just to Google it for example, searching for “OpenSCAD for loop” will get you pretty quickly to the documentation page you need for reference. The best way to learn code is by example, and the OpenSCAD user manual includes example code for all its commands and operations. You should also bookmark the very useful OpenSCAD User Manual and OpenSCAD Cheat Sheet. Start by downloading a free copy of OpenSCAD. But even if you’ve never written a line of code before in your life, you’ll be able to learn the basics of OpenSCAD and get started modeling right away! Even better, you’ll be able to add variables and parameters to your models so that you can customize and modify your designs very easily when you want to change things. If you’re an experienced programmer then you’re going to love this.
