I've had these same angled print lines (if that's what they are) on some recent FUD models I received in mid December 2015. They are very distracting to say the least. I have had the same models printed before without these lines, so I know it can be avoided. It takes some serious effort to get rid of these lines while preserving the delicate printed detail elsewhere.

I would like some guidance from Shapeways on what, if anything, we as designers can do to influence the best finish on our models. Some surfaces of my models I just don't care about because they are hidden. Other surfaces must be executed as accurately as possible or the model is a failure. This has come up in the print orientation discussion but I think it needs to get beyond the scope of that discussion. I shouldn't need to be an expert in 3D printing orientation (and I'm not) in order to specify the surfaces I want to appear the best. It's an insult to the trained professionals for me to tell them how to do their job. Instead, I should be able to specify where I want the best quality surface and leave it to the professionals to deliver on this specification.

The hit and miss nature of this process isn't just tiresome, it's also expensive. I can't effectively make a good argument for people to buy my models if the results they are going to get are so inconsistent. I certainly won't get repeat customers if the model is a failure. I am going to buy a certain amount of my own designs for myself. I can choose any 3D printing provider for that purpose and quality is the primary driver in that choice. Shapeways offers a marketplace to share our designs and to sell them without setting up our own marketplace, keeping inventory, etc. If the quality isn't wrestled under control soon, the benefits of the marketplace will cease to exist. Instead, I will be forced to forge a new reputation with another vendor.

It's as if somebody (possibly another shop, if SW outsourced these wacky prints, or a new SW employee trained by some other shop) has only one concern- that of minimizing support material, to the point of totally disregarding print quality and customer satisfaction.

I'm still cursing as I clean up a $100 model that was printed like that.

Please, SW, enable print orientation (for those who know enough to care) and be done with this crap!

It would probably help to know which software you are using, but in general it should work if you just treat the unknown units of your software as inches, i.e. model your part as 2 units high. STL is dimensionless anyway, so will get asked to pick the correct unit on upload - if you choose inches there, the correct size should be shown alongside the model preview (though axes may be swapped compared to your software).
