Cant get ceramic option!

My model has an obvious base. But the preview shows it sideways and needs to be rotated 90 degrees. Is the problem? or is it that my piece has a hole? (torus coffee cup handles print so it cant be that reason). Any help would be appreciated.

Attaching a file in a post does wonders In allowing others diagnose problems in a model. I am not trying to be a SA, but it does help considerably

Enclosed here is the file. I guess linking to the uploaded stl file would be better..

Edit: I added chamfers where I could since I cant get a good fillet tool for sketchp

Exporting DAE from Sketchup flips the model by 90 degrees. If you rotate the model in Sketchup before exporting, it will show up correctly in the Shapeways render...

Two other possible problems...the model isn't solid, and the hole thru the model isn't filleted/chamfered.

Use this plugin for checking solids in Sketchup, and use this one for filleting corners in Sketchup.

Ok for that: I got the proper orientation. thanks but no ceramic option yet

Ok thanks, I got both plugins and that produced the filleted geometry (1/16 and 1/32inch radius). (see link http://shpws.me/n7JZ) But as seen here, solid inpector shows the piece is actually two parts! cant seem to get them glued...

You need to make the model page available to others for us to see it
But I'm guessing the item is either too small or too big, from Ceramics Design Gudelines

There is an internal face in there that needs to be deleted...you may have to Select all > Right Click > Intersect faces with model to delete it.

As Paul suggests above, I think your part is too small for ceramics.

Thanks for letting me know. Fact is, the materials page only mentions max size.

If you click the "Design Guidelines" tab, there is more detailed info available, including the minimum size...

Yes I redid the fillets in Sketchup and deleted the offending face inside the part by deleting the base face then putting it back after correcting.
When I re-uploaded to my account, still no ceramic. I doubled its size in Sketchup then reuploaded NOW IT WORKS!

Unfortunately I need the part to be 1.25in diameter not 2.5!

My solution: combine two identical parts joined with a breakable flue

EDIT: actually a connecting rod is not necessary, ill just put 2 parts in the dae file.

Ok thanks the design guideline TAB details it quite well
