I feel you. Replace “little one” with “neighbor” and “basement” with “garage” and that’s where I am.
Anyway, I just wanted to highlight that the reason I mentioned the online version of @fenrus’s tool is precisely because it’s a major shortcut to avoid having to understand and deploy the other goodness he put up on github: it literally takes a few seconds to upload an STL, save the generated heightmap, and import that in CC. I remember doing exactly that in this little project of mine, picking up an STL from thingiverse.
I wish @robgrz would integrate his (or similar) code in CC Pro as an “import STL” feature, it’s a killer feature in terms of productivity.
