System Information
Windows 8.1, GTX 570

Blender Version
Broken: 2.73 b4d8fb5

Short description of error
When I tried importing and FBX or OBJ file in blender and I want to change the Up axis of the file when I select the "Z Up" option it changes to "X Up", Likewise with "-Z UP" it changes to "-X Up"

Exact steps for others to reproduce the error
Open Blender.
Select File/Import/OBJ (or FBX, is probably broken with all importers I have only tested these 2)
In the import screen select and OBJ or FBX file, and chose the UP: options of ether "Z Up" or "-Z Up" you will immediately find blender has selected "X Up" or "-X Up"

That is indeed weird.

@JulianEisel, mind having a look? :)

Doh I'm an idiot, didn't notice that Z Forward was selected so when I selected Z Up it just would jump back to X Up.

Would be less confusing if you could select Z Up and blender would change Z Forward to another value.

The opposite seems to work, For example lets say Its set to:
Z Forward
X Up

If I change "Z Forward" to "X Forward", blender automatically changes the "X Up" Value to one of the other two options.

@guategeek, yes there's indeed some degree of confusion here. Worth checking for usability improvements here.

So you mean everything works as you'd expect it now?
We could make this change automatically, just as you suggested, but we normally try to avoid such things so it would be really inconsistent on how Blender normally works

Do not see how we could improve this, you can't have same axis for both up and forward, and you cannot make two props update on each other (leads too easily to infinite recursion…).

Anyway, definitively not a bug, you get same behavior in constraints using axes e.g.

Ok thanks for the info, and sorry about the mistake on the bug report. UI wise it would be great if the option that's already selected for the forward axis is grayed out in the up axis.

@mont29, first ever idea which comes to mind is to let setting whatever value you want to any of those menus and tweak value in unchanged menu to keep orientation consistent. That way you are not forced to use specific order of modifying the settings.

@Sergey and how would you tweak other setting in a good way? How to choose among the four remaining possible values? Or do we just accept to select first available (possible) value?

Also, constraints & co just let people select whatever axes they want, and go in 'invalid red' status if settings are incompatible… :/

Mwua. What's wrong with setting first option which doesn't lead to conflicts? That way you're not ending up with setup which doesn't make sense and still don't restrict options set order.

Done.
