I spent a lot of time building up my armature for my dragon model and then, after I was all done and started to refine it, I realized that the bones from the pelvis out to the end of the tail were pointing the wrong way - they need to have their heads pointing the other direction:

Armature with bones pointing in the wrong direction

I don't want to have to delete these bones and start over.

Is there an easy way to switch the direction of the tail bones?

Switch Direction of Bones

Thankfully Blender has a simple command that will reverse the direction of selected bones called "Switch Direction". You can access this two different ways:

  • Select rig > Tab > select bones > Specials menu (W) > Switch Direction

  • Select rig > Tab > select bones > 3D View Header > Armature menu > Switch Direction

enter image description here

    $\begingroup$ Thank you for pointing that out! I had been looking for something to "Reverse direction" ("Switch" never occurred to me) and I was also looking for a Bones menu item in Armature, i.e. Armature -> Bones -> Reverse Direction. $\endgroup$ – Thom Blair III Apr 26 '14 at 10:08

Blender has a function to switch the direction of Bones, however its worth noting that there is also the ability to select a bone chain in one step:

  • Enter Edit Mode Tab
  • Select a bone on either end of the chain you want to flip RMB
  • Hold Ctrl and click RMB to select the other bone in the chain.
    (this selects bones in between, matching similar behavior in mesh editmode)
  • Armature menu > Switch Direction (or AltF)
