1.1 Let’s start from the beginning.

First of all you need to focus on the section of the tower: rectangular, circular, elliptical or any kind of strange shape that you can think. In this project we’ll use elliptical section, the same that you can use as a base for a stadium.

The is important to focus on how to mathematically construct the shape so is better to deconstruct the shape in simple curves like lines, arcs or other mathematical functions. For this project we’ll use a very simple mathematical function to construct something like an egg but, to keep it symmetrical, we will create both side of the egg like in the picture below. The formula is not really complicated but, to be able to use this formula in Dynamo you need to convert in ”Excel like” way.

Everything must to be in one line using only parenthesis:

((R-r)² - a²) \/ (2*(R-r))

R = radius of the major circle

r = radius of the small circle

a = distance between the circles center points

P = R – y
