Geometry central point objects

I have a object a car with objects like a door wheels etc. The have all a object center to mass but now the object must change to object center to geometry how can i do that.
Hope i have asked it right.

Object → Set Origin → Origin to Geometry

Yes I forget some objects to apply the mirror setting
but know its good, Thanks

So this went well… and usually then the X value can be changed to 0… :stuck_out_tongue_winking_eye:

Oke to have a secure center point i guess

Geometry its a lot of math unfortunately not for me.
