SketchUp on the iPad. This sounds pretty interesting to me.
I have tried several 3D programs on the iPad. Shape3D and Umake
for example, but both were too clunky for me.

Currently I have Nomad 3D installed on my iPad and am very happy
with it. Nomad 3D is actually known as a Sculpting app. But it can do

It is from Ilya Tulyakov, in this video he switched between
Nomad 3D and Procreate. He use Procreate to sketch some
parts bevor modeling.
A few posts back in this thread, I posted a scooter I modeled with it.
