Interesting, because I am trying to learn OpenSCAD for some simple modeling.

definitely learn solidworks or something in that vein first

that, and as a prior skill, learn to draw by hand on paper orthogonal and isometric views of 3d objects.

cad is another theory building excercise, but instead of being about processes, its about objects. you want to start from a strong manual/first principles base

If you're more interested int the result than the process, Onshape or Fusion are great, free (with use restrictions) parametric CAD. And both support scripting, to some extent.

Both have really great documentation/examples.

Note: This is probably a dead-end; it is not on the same level as SolidWorks, Fusion etc.

  • Or Blender, pen and paper, bag of LEGO, etc. Text in context of geometric object is more or less an abstract classification tool, barely a descriptive one.

    Everyone knows what a `dice` is. But that's a taxonomical label, not a definition of one. Anyone reading this can probably draw a representative `dice` using only standard stationery supplies in under a minute. Now describe one in English with such rigor and precision that it readily translates to a .gcode file to be printed. That requires a good amount of useful neurodivergence to pull off at all.

    • The great thing about OpenSCAD is that one can model anything which one can describe using mathematics and cubes, cylinders, spheres, and transformations/relocations of same.

      The awful thing about OpenSCAD is that what one can model is bounded by one's fluency with mathematics and one's ability to place and transform cubes, cylinders, and spheres.

  • I wouldn't call a FOSS project that you compare to some 2,620 USD/year software a dead-end. It's good enough for simple modeling, especially when it comes to scripting, and has been for 10 years already.

  • You're probably right, OpenSCAD seems to be limited both in speed and in exactness of the surfaces.

    However purely programmatic interface allows doing surprising things which might be hard to achieve with a mouse.

    • If you're using one of the old stable builds, then the newer nightly builds are markedly faster --- hopefully there will be a new stable release presently.

for simple learning, I invite you to consider SolveSpace

  • Has there been any work on it to make it usable w/ touch or a stylus or a trackpad?

    I'm on the verge of breaking down and buying a license for Moment of Inspiration 3D since it was designed for use on tablet computers (which is my preferred sort of hardware).
