There is no command like you mentioned in UDEC ver 7. You will have to write a small fish function to get principal stresses. However, the command “pr zone stresses” lists the principal stresses in the zones.

There is an example data file provided in the datafiles/fish/library/3D_prncipal_stress folder that could be adapted to provide the principal stress for a zone. You can also use the FISH function tensor.prin,
