Not a Problem
1) I would expect that the UI-tool 'Rotate 3D graphics View' should rotate around point (0,0,0).
However, it rotates around point (0, 0, 1.5).
2) When 'moving the 3D graphics view', the rotation point still remains the same point on the screen. I would expect it to move along with the (0,0,0) point.
The same problem 
I think that would be strange - imagine if (0,0,0) was off-screen
Hi Michael,
Thanks for looking into this.
Maybe it depends on the use-case, and how you use the coordinate system. But it does rotate around (0,0) in XY, so why around z=1.5 in the other planes? At least it would be more consistent to do the same in all coordinates?
It will, you just need to make sure (0,0,0) is in the centre of the view.
That will be easier to set soon - try this test link https://www.geogebra.org/m/...
Hi Michael,
The behavior of your test program is OK for me. It would solve my problem.
You can see the current behavior(Classic 5.x) of your test case here while drag-rotating the 3d View.
Fyi: I currently use Geogebra to validate 3D models of human heads by drawing a 3D view over a 2D photo , as in this example: I make the Geogebra window transparent so that the photo acts as a background, and then I rotate the model to check it. For this, I need the rotation point to be stable, otherwise I need to reposition both photo and geogebra all the time.
