I have been working on this sculpt and noticed when trying to mirror that the point of origin for the model has been moved. How do I reset the location of X and all rotations to zero without moving the object?

mirrored object with origin in wrong spot

    $\begingroup$ By the look of it I would say: Shift+S > Cursor to center (if it isn't already) then in Object mode > menu Object > Transform > Origin to 3D cursor. As for rotation: CTRL+A > Rotation $\endgroup$ – Zafio Sep 23 '15 at 2:37

Here's one way which assumes your object is centered over 0,0,0:

  1. Snap the 3D cursor to the object's origin (⇧ ShiftS)
  2. Depending on the orientation of your object, set the 3D cursor's location to 0 along one axis (based on your screenshot you'll want to set it to 0 on the Y axis)
  3. Snap the origin to the cursor (⎈ Ctrl⇧ Shift⎇ AltC)

  1. Apply rotation (⎈ CtrlA) to vertices (this will reset object rotation). enter image description here

    $\begingroup$ Wow. Ctrl+Shift+Alt+C is definitely the worst shortcut I have ever encountered. $\endgroup$ – Andreas Haferburg Feb 1 '17 at 12:57
  • $\begingroup$ @AndreasHaferburg I've never thought it particularly difficult, all the keys are easily within reach of the left hand (on querty anyway). If you prefer, you can click Set Origin in 3D view > Tool Shelf (T) > Tools > Edit $\endgroup$ – gandalf3 Feb 1 '17 at 17:46
  • $\begingroup$ I guess it depends on the keyboard and on the size of your hands. It's not a question of reach, but how much you have to twist your fingers. All fingers are forced to leave the home row. I would never be able to do it blind, which defeats the purpose of a keyboard shortcut. $\endgroup$ – Andreas Haferburg Feb 1 '17 at 22:23
  • $\begingroup$ @AndreasHaferburg For blender I typically leave one hand on the modifier keys and one on the mouse; for non-typing tasks like 3D modeling I'm not sure how the home row has much significance (unless you are trying to make some sort of vim-like keymap for somehow keyboard only blendering :P) $\endgroup$ – gandalf3 Feb 1 '17 at 23:27

Here's two ways you can reset your origin point and both are really easy:

  1. Go to object mode, press and hold [Ctrl] [Shift] [Alt] [C] and a menu should appear. Simply select "Set origin to centre" if you want it to appear in the centre of the grid.

If you want it to appear somewhere else, simply click where you want it to be(so the circle and crosshairs appear there) then do the method above but this time, select "Set origins to 3D cursor" and viola! Your origin point has been moved :)

If you find that a bit difficult, here's another method you can try:

  1. Go into edit mode, select all of the model by pressing the [A] key, then simply drag your model until the origin point is where you want it to be on the model, then simple go to object mode and move the model back to the centre or wherever you want it(the origin will stay there now.
