I am currently working on a jewelry design which involves a number of curved shapes all connected around a central cylinder. The idea is for the cylinder to appear as if it is a pin going through the other shapes. I originally modeled this as separate pieces and planned on using a ProBoolean to attach them all together. This resulted in some serious manifold issues, so I reworked the model to manually attach each piece, and this also led to manifold issues. It all looks fine, but when I check for water tight meshes in AccuTrans it says there are holes, though I still can't find them. I was hoping someone on here could give me a helpful hint to fix my problem. I've tried it a number of different methods with no success and I'm beginning to get a little frustrated. I've attached the model with the separate pieces, before any booleans, so if anyone is feeling helpful please take a look. Maybe I'm just approaching this the wrong way, or making some serious mistake. I'm using 3ds max 2009 in case that matters at all. Thanks for any help!
