I have 7.0.1 at Windows 10 and even I switch F.Cu to be invisible 3D viewer shows my PCB.

I found out, that 3D is there, but paned far away.
Having F.Cu visible, the 3D PCB is centered from the beginning.
Strange, but nothing to put effort in, at least to me.
Maybe if others encounter the same, we should raise a flag.

You can put a zero coordinate point anywhere on the board

1: I’ve tried that, makes no difference
2: That does not explain why the behavior differs depending on wether F.Cu is visible or not.
