Yep, if you have not noticed....
Shapeways has changed the direction it displays your model orientation.
All mine used to be placed so it appear level in Shapeways images, yet in the 3d software I use they was up-down.
Now they will seem to display as per the 3d software, and in colour too.
Great but I wish I had been told of this rather significant change, I now need to rotate all my models so if I need to upload again they have the corrected orientation.
Yes its much better, but past work is affected.
Does mean new work does not need rotation just to look right in the shop.
Also means I got to be more careful on the colours used when modeling, in past it was always shown as grey, so they was only there for me to know what part is what.
