If my MagicaCSG modeling posts have attracted your interest in the SDF modeling method, you might like to have a look at Womp, a free online SDF editor (with a "Pro" subscription option).
I've just played with it for a few minutes, and you can export your scene as an OBJ file, complete with textures for recreating the Womp materials in Blender, as you can see in the screenshot.
