...I like Goxel too, but why does Voxel Max make Goxel better?...

Sorry, my sentence got lost a bit in translation :)
I actually meant it in this way.
"Since Voxel Max was mentioned here. "Goxel" is also a nice voxel editor on iPad"


I had a trial version of Shape3d on my iPad.
Was a bit too technical (CAD oriented) and expensive for me.

I also tried Umake3D once, which allows sketching in 3D space.
Since Umake3D is only available in a subscription and it was often
awkward to use, I gave it up after a while.

So, Nomad Sculpt is my favorite 3D tool for the iPad so far.
