Hey all,

I've been designing a puzzle on Google Sketchup to be printed on shapeways. However, whenever I try to order, an error occurs. Apparently my design has "non fixable shells."

Unfortunately, this is the first time I have ever used both shapeways and sketchup, so I am at a loss.

If anyone is willing to help me, you can download the .dae file at: http://www.shapeways.com/model/250401/i ... tml?gid=ug
Just suggesting what to do would help!

Thanks
Andrew

Nonfixable shells or non-manifold?

Lot of things on fixing various issues. Make sure you merge your solids.

good question... the error message said nonfixable shells, so I'm going with that

That might help

not all shapes have to be triangles, right? (shapeways has a link for netfabb that checks over my design, but it keeps changing all the shapes to triangles)

Pretty much every 3D will create it's slice files from an STL file which essentially is your design represented as a number of triangles. So when you say it changes your shapes to triangles I'm assuming you don't actually mean than your shapes turn into giant triangles?

No no, just if there is a square, the program automatically draws a diagonal.

In Picasa view hidden lines it will show you the triangles.

As in it draws a diagonal line through the square? That's exactly what I'd expect it do...

If you make an stl and want it checking then I'd happily take a look for you - my research is entirely based on 3D printing and rapid prototyping... I could event try a test print if you wanted?

That would be awesome! how should i send it to you (email?)

Thanks Chris for the help!

My design arrived today, and I fixed up the model based on the result. Here's a pic:

The cumulative brain power is scary...
