Interesting, because I am trying to learn OpenSCAD for some simple modeling.
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
Both have really great documentation/examples.
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).
* a keyboard's shift key and a right mouse button, or * a middle mouse button, or * a 3D mouse.
I've done some work in SolveSpace with a Wacom tablet, by binding the stylus's buttons to the middle and right mouse buttons. SolveSpace is a pretty simple program, so you don't need to dig deep through the UI to get to all the functions. Lost of the often-used functions have keyboard shortcuts, but I don't think there is anything that is only accessible through the keyboard.
Depending on what you aim to do, you might be interested in keeping up with Blender's currently-in-development tablet mode:
I'll keep experimenting w/ this in mind for the next time I'm using my Wacom One attached to my MacBook.
However purely programmatic interface allows doing surprising things which might be hard to achieve with a mouse.
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 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.
