I've been making some model train parts, and using NetFabb Cloud Service to boolean join all of the seperate meshes into one single mesh. Unfortunately NetFabb Cloud Service seem to be broken this morning
I uploaded the model to Shapeways anyway and to my surprise a small cylinder (representing the end of a bolt) was removed from my uploaded model. This issue has been raised before, but obviously still remains.
For me this is not such a big thing as I know what I need to do to before uploading - it just a pain and will take me longer to complete the model
For others, this could be the difference between a happy Shapeways customer and an angry ex-Shapeways customer.
Nope, the seperate watertight and manifold shells overlap by 0.15mm and share no common faces.
Here's a screenshot,
Here's another example of disapearing small yet acceptable shells, both are the same model, the first was sent through NetFabb Cloud Service before upload to Shapeways, the 2nd uploaded straight to Shapeways. http://shpws.me/lo4d and http://shpws.me/mMtn - I've set the moodels to be downloadable, and you can see from the 2nd one that parts are removed
Just received note from our development team!
"Netfabb removes ghost shells that are too small to be printed even if the shells intersect larger printable shells. What netfabb should do is merge intersecting shells before removing any left over ghost shell. "
We are working on a fix which hopefully fix this issue in the near future.
However there are some issues with the newest software so we want to make sure it's a stable version before updating.
If you would like, you can email me (mitchell [at] shapeways) and I can send you the merged shells file which should upload fine
