Answer:
Depending on the orientation of the lines/members in space, the coordinate systems along the line or member may be different. You can find a detailed definition of the orientation by clicking the link below this FAQ. In order to unify the coordinate system, the line or member must have an identical member rotation. For curved objects, this is only ensured if they are rotated via a help node. For this, select "Inside" as the node number. The plane can be defined using the options "x-y" and "x-z".
Question
I have modeled a curved line or a circle, but its axis system has a different length or circumference. What is the reason, and how can I unify the local axes?
