I have tried to set the origin of a mesh using Origin to Geometry, Origin to Center of Mass (Surface) and Origin to Center of Mass (Volume).
None gave me the correct result.
What am I doing wrong?

- $\begingroup$ I'm not sure I follow, but you can position the 3D cursor to where you want the origin to be and set it there. $\endgroup$It's Just Chris– It's Just Chris2020-02-27 21:38:43 +00:00Commented Feb 27, 2020 at 21:38

3 Because your mesh is fatter at the bottom than it is at the top, the center of mass by volume and by surface are toward the fatter end of your mesh.
Your best bet is to position your 3D cursor where you want your origin to be, and then set the origin to the 3D cursor.
In Edit Mode, select one vertex on each end of your mesh. In your case this is easy because you have conveniently centered vertices.
Hit SHIFT + S and choose 'Cursor to Selected'
In Object Mode, set the Origin to 3D Cursor.
- $\begingroup$ What a great tutorial. Maybe I ask you which numpad key you have used to show the model in frontal view? I have used 1, and that showed me the bottom. Edit: I got it: 7. $\endgroup$tmighty– tmighty2020-02-27 22:07:35 +00:00Commented Feb 27, 2020 at 22:07
- 1$\begingroup$ Good answer :). Just to add - since 2.81 you can directly move the origin point with the Move Tool. It's faster in some situations. $\endgroup$jachym michal– jachym michal2020-02-27 22:25:57 +00:00Commented Feb 27, 2020 at 22:25
- $\begingroup$ @tmighty Numpad 1 is Front view, and Numpad 7 is top view. In Blender 'Z' is up, not 'Y' like in Unity for example, so your model is technically lying on its side. You could rotate it 90° about the X axis to get it upright. $\endgroup$Rekov– Rekov2020-02-27 22:52:04 +00:00Commented Feb 27, 2020 at 22:52

I understand that you want the origin to be at the centre of the bounding box. Origin to Geometry will do this if you first set the transform pivot point to Bounding Box Center. (The button for setting the transform pivot point is the second of the four buttons near the centre of the 3D Viewpoint header.)
