Hi All,
Sorry, I should have been clearer about the problem. The error message in this case is about my normals being flipped. Usually I have to deal with manifold issues so this is a change of pace for me.
I modeled the meshes in Rhino from a point cloud, and built the solid to be a single mesh. I used CheckMesh and RepairMesh to fix several small 'naked edge' problems, and Checkmesh gave me a clean bill of health from Rhino. UnifyNormals reported that all normals are pointing in the same direction, and the little arrows all seem to indicate that the normals are all facing out. Extensive visual inspection of the model (with colored backfaces, etc) do not reveal any issues.
Meshlab similarly reported no errors, no non manifold points or edges, and the normals all seemed to be okay as well.
As for the size of the object, I don't have the model in front of me, so I can't give an exact dimension. I intended to print the model on the shapeways machines, so I think it was 6" x 8" or so.
Thank you in advance for any assistance you can provide. It never ceases to amaze me that people all over the world can help out with these technical problems via the internet.
Thanks,
