Hi Michael,

Thanks for the compliments.

Being only new to all of this CAD stuff, my greatest difficulty was doing the design & learning how things worked.
The Mesh Cross & all of it's various changes for the customer, occurred across a number of the Betas.
But from memory there wasn't anything specific that was difficult to do, just me learning the right way to do it.
To be honest, I don't think I'd have had the same successful result if I'd tried to use Rhino. (I'm to new at it)

I exported the Cross directly from MoI without any problems.
Mind you, I did export it at the maximum settings to be on the safe side.
My milling software had no problems with importing it & the finished wax looks fine.

As a point of interest, I spoke with the one of the guys who was doing the RP for the Fusion Bangle.
He was quite impressed with the STL file, mostly because he didn't have to do anything with it at all.
Apparently with most of the STL files he gets, he needs to tighten them up & make them water tight.
I just exported it at the maximum settings, so I guess your STL export works a real treat.

I'd only just started learning Rhino when I was introduced to MoI. (Dec. Beta)
I've done far more with MoI because I find it's easier for me to understand & use than Rhino.
By doing it this way, I've now found that my basic understanding of things in Rhino has also improved.

regards Colin
