# Bone snapping to control bone while making an Inverse Kinematic Rig

Good evening. I have made a humanoid rig and wish to add an IK Controller to the bone "UpperArm.R". I wish to make the bone "CTRL_1.R" bone as a controller bone. Whenever I do so, the control bone snaps to the bone "UpperArm.R". A blend file has been provided. Please look into this. Thank you.

Your problem has a very simple answer. When ever you add IK control to a rig, the default chain length is usually $$0$$ and the bone tries to point at the rig's origin, thus creating some weird posture.
Try $$1$$ or $$2$$ and get a feel of what work best for the rig.
