The cross-section plane is, by default, perpendicular to the element axis connecting the centers of gravity at the element begin and element end. In some cases, it might be advantageous to define the cross-section in a different plane. RM Bridge allows for defining the cross-section in any plane. However, the cross-section properties are calculated in this plane and used in the stiffness calculations without any transformation. However, the plane specification influences the position of stress points and tendon points in the tendon geometry calculation process and in the design checks.
