Shapeways: Bring your creativity to life in 3D http://www.shapeways.com/forum/index.php Shapeways: Bring your creativity to life in 3D automated checks http://www.shapeways.com/forum/index.php?t=rview&goto=52965&th=10609#msg_52965 I'm a bit of a noob at shapeways but I am a very experienced 3d artist...

I recently submitted an printed a couple of very cool test pieces. One is a bust the other a small logo, both came out great!

However my most recent piece, a small ring, is getting kicked back to me with a very generic message from shapeways saying the asset did not pass their 'automated checks'...

What are the "automated checks" that shapeways performs? I've checked the asset here in 3dsmax and zbrush, my wall thickness is larger then their minimum specification. I even went through the asset and removed 90% of the detail, reducing it down to a very simple torus shape with and it still fails the automated checks...

I've emailed the service@shapeways.com address with my files but I'm wondering if any users here can help shed any light on what my errors could be? As they seem slow to respond.

I don't have any open faces, inverted normals, floating verts, my scene scale is correct and I've run mesh checks both in 3ds and in zbrush to verify.....but it still fails "automated checks" ... very confusing...

Anybody know what I could be missing?

thanks

AFAIK, the automated checks by Shapeways' Mesh Medic are;
Mesh integrity, for watertightness, manifold errors, and inverted normals.
Bounding box size and wall thickness for material options.

NetFabb Studio Basic has a suit of features that can help you track down the issue - if just a basic torus fails, I'd be looking at the measurement units used in both creation and upload. Generally as long as a model has bounding box sides of 2.5mm or more, then it will be printable in at least one material.

I've tried out a few models that I know will been thrown out due to errors. Did the message you receive look more or less like the text below?

Quote:

Uh oh! Seems like your model needs a bit more love before our robots can work their magic.

The 3D model <*your model name here*> you recently uploaded didn't pass all our automated checks, so it's not yet ready for 3D printing.

Our tutorials and FAQ can be super helpful for more detailed information, or you can always ask the community a specific question on our forum



This message appears to be the only one that does not state what the error is, however the model I uploaded has 1.3 miilion triangles which exceeds the 1 million triangle limit.

If your message was the same, reduce the triangle count to below 1 million and you should be good to go.

Note to mods, may want to make a sticky on the 3dsmax units setup thing... I made another post explaining the issue.


thank you guys for the help!

cheers
