How to select CID during CBUSH creation

GE4130

I don't see how to select an orientation coordinate system while creating a CBUSH element on the springs panel. When using coincident nodes the CBUSH must be oriented by a coordinate system. Can someone tell me the way to set the CBUSH orientation CID from within HyperMesh? My model will only work by editing the input (*fem file) manually.

Card edit CBUSH elements and refer the LCS under CID as shown in attached screenshot.

How to update CBUSH element.

I want to swap its orientation from N1 to N2.

The vector orientation method works the same way for CBUSH’s as it does for CBAR/BEAM. For vector orientation:

Element x axis will always be the direction defined from node A to node B on the CBUSH
Element y axis will be defined by the perpendicular component of the vector you define with N1N2N3. Are you comfortable with how the N1N2N3 collector works?
Element z axis will be cross of x,y
Align with the local system x axis
The N1N2N3 vector you define will align with y
