    Hi

    You Need to define the N1,N2 and N3 to have the local coordinate system when using /SECT/PARAL

     

    you could add for instance in the /NODE

    #--------------------

    /NODE

         1001               25.0               115.0               -1.0
         1002               25.0               115.0                1.0
         1003                0.0               115.0               -1.0

    #---

     

    and on /SECT/PARAL
