For something so simple there are surprisingly little Google results, likely because I'm a noob and everyone already knows how to do this.

I have imported a Collada DAE 1.4 file, that I made in another 3D modeling tool, into Blender. In Blender, the model is shown very large, and it isn't centered at the origin. I want to start by moving the model to the centre of Blender's grid.

However, the model file contains multiple objects, and I'd like to keep it that way. I knew to centre an object, you can go Object>Geometry to Origin. The problem is that every selected object gets moved to the centre of the grid with total disregard for every other object around it.

The model as it should appear

I am aware there is some z-fighting going on, but I will fix that after my model is centered and scaled. Here's the model as it should appear. The 3D cursor is way off in the background behind the skydome, in its original position at the centre of Blender's grid, and I want the centre of this model to be there.

Here is how it looks when I select every object and do Object>Geometry To Origin. the model is wrong

Yes, everything is centered, but no longer is the model laid out the same way as before. Instead, every single object is now at the centre, instead of there being a sort of "bounding box" put around everything and centering the bounding box instead of each individual object. The wings, which were in its own object, are at the centre, and the tail, which was its own object as well, is now also in the centre - rather than remaining attached and being treated as if one object.

I could just combine every object using Ctrl+J. But I'd like to centre everything while keeping the objects separate.

Either select all objects, center the cursor with Shift + C and then use Shift + S > Selection to Cursor (offset); or if that doesn't work:

  1. Select all objects with A
  2. Clear their relations by removing parenting with Alt + P
  3. Center objects origins with Shift + Ctrl + Alt + C > Origin to geometry
  4. Now select all objects again with A and then Shift Select one last large object (like the ground or the scene background or whichever you want to be at the exact center of the world) by clicking on it to make it the active object
  5. Press Ctrl + P to parent all other objects to that one
  6. Now you can move that active "main" object to the scene's origin with whichever method you like more without breaking objects relative positions.

Either With Alt + G or with Shif + S > Object to origin or by manually entering or clearing coordinates.

You can then release the parenting if you no longer need it afterwards.

Edit: Have in mind that this may break any meaningful relationships you might previously have between your objects

  • $\begingroup$ Hmmm, I don't get an option for Origin to cursor when I press Shift+Ctrl+Alt+S, instead it opens the Shear panel. I should mention I'm using Blender 2.74 and I havn't edited my hotkeys. $\endgroup$ Apr 30, 2016 at 3:48

To move an object to the center first press "Shift+C" this will move the virtual cursor to the center. Then right click the object and press "Shift+S" and select "selection to cursor.

Another way of going it is by first selecting the object with a right click then press "G" then press down on your scroll wheel and move the mouse in the direction you want it, release the scroll wheel, move the object and left click to confirm.


  • $\begingroup$ So the object has to be centered manually? Pressing Shift+C just seems to zoom out the camera to frame the model, and then pressing Selection to Cursor creates the same problem I described above. Every object is moved to the center, but not in relation to one another's previous position. $\endgroup$ Apr 30, 2016 at 3:10
