Model not facing front in shapeways image preview

Not sure what I am doing wrong but I made a few models in Sculptris and in Sculptris they are all facing the front but when I upload them to shapeways they are all facing upwards.

What am I missing?

The issue here is that the "up" axis in 3d software is not uniformly defined.
For some it's Y, for others it's Z.

The easiest solution is to pre-rotate and update your model on the site.

I actually tried to pre-rotate the model and the preview was unaffected, any ideas?

Eh no, then I'm a bit stumped.
So regardless of orientation it ends up wrong in shapeways?
Can you see the change in rotation when you view the model in other software like (free) meshlab?

Try orienting in Blender. I've seen some weird orientations out of Sculptris OBJ export.
