That's when your programming and mathematical knowledge will be required.Īs a small PS note: my personal taste is, depending on the part I want to make, to use either Tinkercad, Freecad or Openscadīlender is a free professional level application, where maths isn't particularly necessary but can be used to good effect, and its minimum requirements aren't all that excessive (my copy of Blender runs on a maxed out 20 year old Dell 380): Minimum (basic usage) hardwareģ2-bit dual core 2 GHz CPU with SSE2 support. The last increment of complexity is that those community objects are actually made using JavaScript (with their own API, it's not related to openjscad) and you can create your own objects by using their interactive JavaScript interface. Then there is a very large collection of more complex shapes provided by the community (screw, stairs, tree) that tend to be very useful to create specific things and a very important aspect is that those shape usually have some parameter you can adjust at the creation of the object (say the thickness of the trunk and the number of branches of your tree). It works the following way : you are provided with a dozen basic shapes (cube, sphere, etc.) and you create your model using boolean combinations of those shapes and translation, rotation and scaling. Here is a screenshot of the interface and a part I made using the basic tools : The interface is trivial to use and there's a 15 minutes tutorial that guides you over everything the software has to offer to the common user. The software I began with was Tinkercad, it is a fully online solution that is very beginner friendly. One gets used to it and error count quickly is reduced.
Syntax and punctuation errors would be eliminated with BlocksCAD, while it's far too easy to create such errors in the editor for OpenSCAD. It may be better suited for younger model makers in that respect. I'd been using OpenSCAD long enough that I found BlocksCAD to overly complicate the creation of models by obscuring details. If you look on Thingiverse using OpenSCAD as a search term, you'll find others' code available for examination and integration into your own models.įor the folks who are not so much into the math and text and logic, there's a GUI of sorts for OpenSCAD called BlocksCAD that allows drag and drop of various modules in a manner akin to Scratch programming. It meets another qualification of yours in that it's free and there's quite a supportive mailing list/forum for any questions or difficulties that arise. I use quotes, because I'm not skilled enough to qualify it as a true compiler, although it works in a similar manner and may indeed be a compiler. It's more or less a scripting/descriptive language "compiler" that takes ordinary text and converts it to your model design. If you've not yet explored OpenSCAD, you may find that it meets your qualifications. I don't have a heavy math background, but enjoy using such skills when applicable.
