Day 34: Procedural modelling part4

I started with the completed model from Part 3 . In this part of the tutorial is more concentrated on how to create a  Tier support.
It adds new division like
Tier length, Tier Width, Tier position Y
this is a physical division of the tier

Tier thickness, Tier Edge radius, Tier Support Radius, Tier support Division
this is an individu; size and position of the tier.

All the above position and link together to create a final tier support.
