Get cylindrical coordinates of a node

Altair Forum User

How should i get these X1, X2 and X3 values for a selected node in the image.

If i use 

 hm_nodevalue $node_id

It returns me X,Y,Z values as per WCS.

But what i want is to get as shown in this window. 

Or may be if i can get local CSYS reference axis.
