Thank you Roberts_clif, I've not had any experience with this sort of thing, We only use CAD at our company to design items, make sure they will fit in an assembly and make a 2D drawing for our toolmaker or fabricators. This is an interesting experience that's for sure. Also may use it to show my company the benefits of 3D printing for certain instances.

I have also had a little go with an automated CNC machine, however with that as I'm sure you know more than me we had to basically tell the machine how to machine the item, I thought maybe this would be the same?
