Hi Michael,

Thanks for that I have changed the axis values but as you note (but will not change how data is actually stored in files) the file moving across into SW orientation is still flipped. Under SW2018 the new file exchange feature allows importing referenced files. Which means moi can be used as a modelling companion to SW and still keep the original file for editing and updating rather than just an straight import. I have changed the Nurbs Import and via a STEP import from SW>MOI orientation is correct. Is there no other way to correct the orientation to go from MOI>SW?

thanks again.
