This is the main process taken to blend together the drain detail. The text node is used to make the majority of the shapes with curves to tweak the profile.
This is the process of combining the different elements and rings together, it shows how to get the shapes to line up. It also shows the process of getting a plastic underneath to the brass to bed the drain in more.

I was inspired to create this marble floor drain which is referenced from inside the Vatican.
This was to test the new Substance Designer 6 and its tools. I created the majority of the brass details using SD6 text and curve nodes.
