If it is not too complicated, maybe showing greyed out the total number of selected nodes, as it’s done for node sets, incl. the resultant force?
well, it does not apply in PTC Creo (link) and i can image how is complicated inside.

How do code in calculix for transverse directions as well provide a torsional stiffness in x y and z. Calculix card which would help me to create this?
Yes the stifness value was very low,
shear stiffness seems possible to represent by using two node spring elements and local axes definition, but can not directly in rotational stiffness due to CalculiX limitation.
Here’s a discussion about it on the CalculiX forum: Torsional Spring - SPRING2? - CalculiX (official versions are on www.calculix.de, the official GitHub repository is at https://github.com/Dhondtguido/CalculiX).
it seems my proposed approach by eccentricity and rigid body to represent rotational stiffness can not work properly at connecting with beam or shell element, end moment of these elements did not transmit in CalculiX. May required general multipoint constraint (MPC) definition by equation, and probably get conflict with rigid bodies when existed.
Thank you, how do I define the shear stifness on the nodes, in the calculix codes, do not find it in the calculix manual
