Depends whether the exporting system is Y-up or Z-up by defaut, or set one or the other way manually.
Another way to think of it is - which view is the logical ‘Top’ or ‘Right’ view for the design/discipline. Depending on Y/Z- up direction, these get flipped, i.e Top is Front, etc.
Indeed. Keyshot allows user to define the Up orientation at import (X, Y or Z), and Fusion allows the default orientation to be defined as Y or Z up.
Yea, I’ve been bitched at by Creo and SW guys on stuff out of Rhino being at the ‘wrong’ orientation, and receive stuff I ‘flip’ in Rhino. On the other hand, the reasonable MCAD guys paying attention to such just roll with it, and leave the original orientation alone so stuff can flow back-and-forth without a repetitive flip/flop game.
@lordarchiebald - for now you might try and ‘negotiate’ a Z-up workflow with others if appropriate and if they are game.
