Align orientation in Pose Mode I'm trying to do a simple manipulation that I'm doing every day at work as a professionnal animator. My experiance is with Motion Builder and 3dxMax, but I'm learning Blender on spare time. 

I just want to align in Translation AND rotation my IK bone to my FK bone in Pose Mode. My ultimate goal is to continu my animation with a precise exchange between IK curve and FK curve when it's time to switch between IK and FK.

I can use the CTRL+S->Cursor To Selected  /AND/ CTRL+S->Selection To Cursor to align in position my IK bone, but what can I do for the rotation? I cant eyeball this, it will create so much trubble down the road...







Thanks for your answer!!
Since I dont realy know how to make Mzidare answer in comment the real answer to my question, here is his reply:

«You can use Rigify, it has IK/FK snap button. If you want to use your own rig though, you would probably need to use a script for that. – Mzidare Sep 2 at 10:22»

Thanks!
