As we know ，In the Blender software, there is a function to move the geometric center to the origin and move the origin to the geometric center. Is there a way to implement this function in Slicer? If I use the Creat models module to creat a sphere ,is the centre of the sphere the origin ? Thanks…

You might be looking for the “Center 3D View” button https://slicer.readthedocs.io/en/latest/user_guide/user_interface.html#d-view

Thank you for your answer. Actually I am trying to find out the whole 3D view’s origin ,not the visible 3D view’s centre.

Can you explain your use case a bit more?

The 3D view’s origin is always at (0,0,0) in the renderer coordinate system (also known as RAS or World coordinate system).

When I use Transform module to rotate a model , I want it rotate along a fixed point , I know the point is the 3D View’s origin. For example , a puncture tube for brain hemorrhage, after I fixed one end ,I can use Transform module to rotate the other end anyway so that find a better path .
