Parametric diamond ring

Hi,

I start GH this last WE, so thank you to be lenient in your reviews.

Here is my first real project. Maybe nothing complex for most of you but I have some issues... And I can't go ahead without your help.

1/ Boolean Unions fails at the end and I realy don't understand why.

2/ When I set number of diamond at is maximum RevSrf fail, I try to limit the domain to 2Pi... It doesn't work. If you can help me on this point.

3/ I now have to build a specific tool to drill ring every single diamond. Ø of hole have to section of this revolution tool have to grow according to diamond size. And for this I have no idea.

4/ Last question is about sharpy edges... On rhino I can add fillets, but here we can't.

Is there a mesh polishing tool or trick?

Thanks a lot

1. Your Gems cluster produces a mesh, not a BRep.

2. I am not understanding how you generate the arc for the gems, but the attached file spreads the gems out evenly over 360 degrees.

3. Drilling machine will require a points and normal vectors. Give ArrPolar the same parameters used to position the diamonds, but use a point instead of a gem object. This will give you your points. The normals are just a vectors from origin to the points.

4. I added components to the attached file that includes a VB fillet routine. (I don't recall where I found it.) You have to play with the 2 Boolean values depending on the 2 surfaces you feed the routine. Also, be aware that Rhino does not handle filleted surfaces well when they come from Grasshopper. To fix this you have to invoke the Rhino command _DivideALongCreases - otherwise your filleted surfaces will have corners in them.
