Coordinate system setup

[spaggioli]

<A name=OLE_LINK1>When our system was set up initially the coordinate system was set up with +Z direction facing out of the screen. This isnow a problem when we export 3d iges files to customers from an assembly.</A> The individual parts use that coordinate system for there output. Can this be changed so the +Z direction faces up and what would be the repercussions from doing this. The main objective is to output 3d iges files from an assembly as individual parts and have +Z direction facing up. I understand I can add a coordinate with the right direction to are assembly but this only works when exporting the file
flat but not when you export the file as parts or levels.

Thanks in advance.
