Project1-Allianz Arena-Mass Modeling

This Project is for the course building information modeling 653 Texas A&M University.

For this project we had to use Autodesk Revit to create a parametric surface and a pattern base envelope. 

I chose the Allianz Arena stadium as a case study. 

the stadium is located in Munich, Bavaria, Germany with 75000 capacity. known for its exterior inflated ETFE plastic panels and it is the first stadium in the world with a full color changing exterior which is the

final objective of the project later on to make this happen parasitically by using dynamo. 

my design intent was to use plan view to create a path then sweep the section of the surface through it. because there was not AutoCAD documents for the stadium I used google earth and some photos with general shape of the plan and the section of the stadium to find relation between stadium parameters for instance relation between the length and width of the stadium

I imported the photos to AutoCAD and created parametric relation between stadium parameters and
the width of the stadium through several reference plains in Autodesk Revit.

when I wanted to sweep the profile through the path Revit did not allow me to create form. I found out that Revit only sweep a profile through a multi segment path only if the profile is actually a close geometry. so I created the stadium platform and connected it to the facade and then I could able to sweep the profile and created the form of the stadium.

Then I divided the outer surface of the stadium and gave it a rectangular pattern.

Next I created a curtain panel pattern based family for the ETFE plastic panels. I assigned parameters for the frame width and length and the skin height and color.
to create the skin I used a reference point in the center of the frame and then I used two other reference points tied to the first point and gave them height parameter and created a form between the points and the reference lines of the frame. for the color I created an instance material parameter to allow me to change every instance of the family in the project so I can change the color of each instance every time I want.

In the end, I loaded the family to the original model and then I assigned the family to the patterned surface.
