Would you define relative rotation between two element ends. Sketch would be helpful.

Thanks Dear Vesna for your reply
but is it possible for a big model?
you mean that there is not any or any command to calculate relative rotation between two end nodes of an element?

There may be a recorder that you are looking for. However, I do not know what do you exactly mean by relative rotation between two element ends.

i think it means, rotation of end of i minus rotation end of j
