# CATCollarBone : Matrix3Controller

    CATCollarBone : Matrix3Controller {68c00456,455634fe}

| 3ds Max CAT - Quick Navigation

This Controller is part of 3ds Max CAT.

It represents the collar bone in the CATrig which typically connects the Arm Limbs to the Ribcage hub.

Constructor:

    Class instances not creatable by MAXScript

Aliases:

    CATCollarBone CollarBoneTrans

Properties:

     <CATCollarBone>.Limb (CATLimbData) : maxObject

Contains the LimbData controller object of the Bone.

This lets you access the limb the collar bone is part of and all related bone segments, as well as the Hub the limb is attached to.

Since the limb has information about the symmetrical limb on the other side of the body, this makes it easy to get the symmetrical collar bone, too.

EXAMPLE
    ctrl = $.TMcontroller--with a collar bone selected, get its controller
    --> Controller:CATCollarBone
    lmb = ctrl.Limb --get the limb data controller
    --> Controller:CATLimbData2
    lmb.Hub--this is the hub of the limb the collar bone belongs to:
    --> Controller:HubTrans
    lmb.NumBones--we can check the number of bones in the limb
    --> 2
    lmb.Bones--or we can get the array with the bone data controllers of the bones
    --> #(Controller:CATBoneData, Controller:CATBoneData)2
    slmb = lmb.SymLimb --we can ask for the symmetrical limb on the opposite side
    --> Controller:CATLimbData2
    slmb.collarBone --and through it we can get the symmetrical collar bone, too!
    --> Controller:CATCollarBone

     <CATCollarBone>.Node: node

Contains the Node representing the collar bone.
