What are you going to be doing with these models? That is to say, once you have your model, are you planning on feeding it to a 3D printer, export it to some other software, create rendered visualizations, perform some sort of analysis? > I had been assuming that 'subatomic through galactic' statement was > good reason to avoid commercial softwares (as well as all other > open-source CAD tools) You can see an example of the larger end of the scale with the “ringworld” demo (only available in source compilations) used for visualization. It creates a model approx 3.06e11 meters wide. I’ve modeled atomic structures myself before for 3D printing demos. > Have I been duped/mislead/ignorant?

Pushing to those limits is certainly possible, sometimes will require creative adjustments, but whether it’s adequate will greatly depend on what you intend to do with the model once you have it. For what it’s worth, I don’t know of any other CAD system that lets you go that small outside of software specialized for exactly that purpose, but maybe something exists. Cheers!
