Reference CID and Analysis CID

Dear all,
I am trying to understand an example model with a bearing.
The two nodes which are used to constrain the bearing give for the Node Location Information:
Reference CID = Global Rectangular
Analysis CID = 4 Rectangular
 
All other nodes are referring also to Global Rectangular CID for the Analysis CID.
I would like to know what this means 4 Rectangular?
The RBE2s which are connected to these points have no reference to other CID so I assume they take the global CID.
 
In the BDF-file there are some CORD2R defined:
CORD2R* 4                              0.             0.
*       0.            1.              0.            0.
*      0.              0.            -1.
*
CORD2R* 5                              0.             0.
*       0.            -1.             0.            0.
*      0.              0.            1.
*
CORD2R* 6                              0.             0.
*       0.            1.              0.            0.
*      0.              0.            -1.
*
CORD2R* 7                              0.             0.
*       0.            -1.             0.            0.
*      0.              0.            1.
*
CORD2R* 12                            -160.81759643554368.5
*      -226.72961425781-160.81759643554691.1295443819 -556.83722631104
*      -168.57967172422698.56095064975695.8543142001753
 
I don`t see a special CID.
Can you explain the 4 Rectangular?
Thanks

  • Thanks Arthur and Darrel,
    Regarding Darrels last remark. In the model I examine, the node for which it is used is the midpoint of a circular rbe2. So the transformation from CID 0 to CID4 does not matter because it is radial. so x and z are the same and y is tangent to this, so I don`t understand why it is used. But ok that is now more in detail of the model you both don`t have.
