a What if System parallel to a spreadsheet but used withing the realm of Building



Several program that implemests a BIM

Archi Cad
usa grasshopper tramite un proprio plugin

precedentemente RadarCh sviluppato in ambiente MAC

Early mac 
Super3d and Strata vision and of course Minicad and later Vector works

TOP solid, pro | Engieer Catia
Gehry techmologies Digital projects

Generative components Bentley extension of Microstation ..
Related to seminars of the SmartGeometryGroup

Sketch up
ha una semplice ma effettiva integrazione BIM / via gerarchica con quello che chiama "componente" Scarica gratis
Procedural modelling vs simple 3d modelling
first to allow procedural / Bim

Rhino e Grasshopper
l'integrazione al BIM avviene con il plug in VISUALARQ sia direttamente in rhino che via grasshopper.

Autodesk Ecotect / GEco plug in for grasshopper _Ladybug + Honeybee
Oasys Gsa highly porfessional as Rhino plug in Kangaroo and Karamba
Human Behavior
search with wikepedia to have a description

Autodesk Revit
Revit che è lo standard Bim più diffuso si lega indietro al parametrico
Un software parametrico integrato che si chiama DYNAMO

Revit è il programma dell'Autodesk che da alcuni anni ha portato l'idea del Bim all'interno di uno standard professionale
The aboveinformation are integrated from the Hyperbody institure experience and research directed by prof. kas Oosterhuis. for an update see Tomasz Jaskiewicz, Towards a Methodoloy for complex adaptive interactive architecture, phd dissertaion TU delf 2013 pp. 211-214

Description of key Philosophy of Revit
Revit’s philosophy - Notes derived from an essay session with Marco Falasca in November 2019. 
Marco has kindly revised these notes integrating and clarifying them. 

Revit is subdividable, at the macro-area level on which to act, in three large compartments absolutely not ponds but interactive with each other: Revit Architecture, Revit Structure and Revit Plant. 
Each macro-area has developed an increasingly integrated and intelligent approach and of course its own philosophy, being each equipped with special plug-ins that allow those who use the program to design, explore, manage and build every minimum component of the specific macro area.
The macro.area closest to us, Revit Architecture, is the richest but at the same time the most immediate and integrable and perhaps to better understand it is good to divide it into two parts.
1. The first is interactive design, that is to say a real meta-design process, which allows us to act on geometries and shapes, and then enrich the information model.
2. The second is the constructive implementation, that is, the design using elements already integrated with the information of the model. 
The one is not chronologically successive to the other, nor excludes it, but you can act for different stages and levels of detail different with one or the other or with both. 

Revit uses the CONCEPTUAL MASS tool in interactive design. The tool allows you to model any type of mass (in fact you can model with splines) acting at the beginning as a real "passive" modeling of the elements and shapes, without for the moment assigning them a label (floor, roof wall..) or a parameter or information.
To this mass Revit allows you to add:

A. Roof systems

B. External vertical latch systems 

C. Closing systems and horizontal partitions

These three systems are absolutely interactive and parametric with the form generated by the conceptual mass: the change of a mass shape can be chosen if the system is automatically updated, for example the roof to the change made before the shape.

The second part is the implementation "constructive" always in the area macrto archtettura Revit uses in this case an infinity of different tools called FAMILIES. Families are the main motor of the nature of the program and their organization is based on a nested hierarchical structure, namely a tree structure. This results in enormous flexibility and management of the building process, and can be implemented with external components downloadable by companies. 

The programme for organisational clarity provides for three substantial levels

A. The level of the HOUSEHOLD
macro-elements for example, walls, doors, windows. Each family (in other programs it is called class) contains within it numerous "types". The family can contain inside other families (nested family), the latter with other types inside them (for example the family "door" can contain inside the family "handle")

B. The TYPE level
the type is what characterizes and gives more information to the families with whom we will build our project. For example, the family "door" consists of many types such as "door to a door", "sliding door", "fire door". 

C. The level of the INSTANCE
The instance adds an additional third level of information to my type and will be exactly the actual element that I will insert into the project model. For example, the type "sliding door", belonging to the family "doors" consists of a series of instances such as "sliding glass door 90x210", or "sliding wooden door 100x230" 
Of course the instance is a 3d description of the object, which has common insertion rules with other systems and of course has a database card linked to it in some cases dynamically. I can get the cost per cubic meter of a certain type or instance of wall and the program knows how to update the cubic meters actually used in my project.

The interactive editing possibilities of course can concern the various types levels (I take a set of recurrences and move it for example) or if I want I can modify the single instance. A further level of project strength lies in the fact that some families need hosts to be created, for example you simply cannot insert a door except in a wall that hosts it, you cannot insert a handle except on a door that hosts it.

In these three levels there is the key to the hierarchical system of Revit, but it must be remembered of course that Revit has its own programming language that exponentially expands its possibilities. The generation process of the families is extremely intelligent - for example those of the plants or of the electric networks or of the structures - which are always incorporated in the project in an interactive way but following the rules of each family.
