For anyone who's had their eye on Groboto or Mesh Fusion from Modo because
of their Boolean functions and blending feature.

An SDF modeler like MagicaCSG can do more or less the same thing.

Substance 3D Modeler is also a good SDF modeler with a good feature set.
There's a Steam version without a subscription, (ca 150.- euro)
with this Version you can model like in a desktop app, but also with VR headset
in VR.

I recommend to take a look at Youtube, there are a few videos
about how to model in Substance Modeler and in MagicaCSG.
