I have modeled a curved line or circle, but the axis system is different over the length or perimeter. Why is that and how can I unify the local axes?


Depending on the orientation of the lines / bars in space, the coordinate systems along the line or bar may be different. A precise definition of the alignment can be found in the link below this FAQ. To unify the coordinate system, the line or bar must have an identical bar rotation. This is only guaranteed for curved objects if they are rotated by means of an auxiliary node. For this purpose, the node number is "Inside". The layer can be set with the options "xy" and "xz".
