What are the local axis directions when +Z-axis is vertically up in AutoPIPE?
Local Axis directions when Y-axis is vertically up:
Local Axis directions when General Model Options, Vertical axis direction = Z-axis will be identical to above orientation. Again local axis is not dependent on General Model options "Vertical Axis direction" setting. This is by design.
