I have modeled a curved line or a circle whose axis system is different over the length or the circumference. Why is this how and how can I unify the local axes?

Answer

Depending on the orientation of the lines / members in the space, the coordinate systems along the line or member may be different. You can find a precise definition of the orientation in the link below this FAQ. In order to unify the coordinate system, the line or member must have an identical member rotation. It is only guaranteed for curved objects if they are rotated by means of a help node. For this, select "Inside" as the Number node. The plane can be defined with the options "xy" and "xz".
