How is orientation preserved for radially replicated frame members?
Answer: For the initial unrotated model, the orientation of frame local axes should be defined using the Advanced Axes option. Two joints should be specified to control member rotation within the 1-2 local plane. Local-axis definition will then remain preserved after the frame rotates. To rotate the model, please ensure that Local Axes is selected and Rotate Local Axes, Where Applicable is not selected.
