question on using zerolength section element in 2D

Post by baozai »

Hello, all:

I have a question on using zerolengthsection element in 2D. I think the default orientation of zerolengthsection in 2D is horizontal x axis. If I want to change the orientation to vertical direction, is there anyone help me how to define the orientation vector?
Thank you for the help.
