How to Describe Computational Design ?


a = 2b = 1

a – b = c

Parametric Design

f(x)


a = 2b = 1

a – b = c

Ways how Computational Design changes your life

▪ Explore multiple design options

▪ Look under the hood of your model

▪ Automate multiple tasks

▪ Test what your design REALLY does

▪ Think algorithmically

Computational Design with Dynamo


▪ Quickly explore parametric design concepts

▪ Solve complex geometric problems

▪ Evaluate designs and analyze geometry

▪ Automate repetitive tasks

Value Proposition with Dynamo


Dynamo Platform

▪ Open Source

▪ Hosted in

▪ Revit

▪ Advance Steel

▪ Standalone version

▪ Works outside of Revit

▪ Connects with the cloud

▪ Included in AEC Collection


Visual Programming in Dynamo

▪ Individual tasks are embedded in “nodes”

▪ Each node on the canvas has its inputs and outputs.

▪ Connect the in- and outputs logically with „wires”.

▪ The effect displays on the graphical background


Packages

▪ 700000+ downloads
