Class Summary
During this hands-on lab you will:
▪discover a whole new way of modelling and analyzing structures
▪learn how to create complex structural steel models with Autodesk Dynamo and Autodesk Revit
▪discover how to rewire your analysis system using Autodesk Dynamo and Autodesk Robot Structural Analysis Professional
▪finally get surprised how easily you can handle almost any complex rebar design in Autodesk Revit with Autodesk Dynamo
How to describe generative design?

Designer/engineer uses computer as passive machine
THE OLD WAY
Computer and designer/engineer
unite as cocreators THE NEW WAY

•Create novel geometry
What is computational design?
a = 2
b = 1 a –b = c
f(x)
a = 2
b = 1 a –b = c
Conventional Scripting
Scripting in Visual Programming

Visual Programming
Computational design with Dynamo
Value Proposition with Dynamo ▪Quickly explore parametric design concepts ▪Solve complex geometric problems
▪Evaluate designs and analyze geometry
▪Automate repetitive tasks
Dynamo as a design amplifier
+=
Design Dynamo Power
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
Dynamo Platform
▪Open Source
▪Available in Revit ▪Freely available ▪Standalone version
▪Works outside of Revit ▪Yearly Subscription

Practical use cases
Computational Design
meets Structural Steel Design
Design of complex frame structures
1.Select the mass roof surface
2.Get the isolines and their translated lines
3.Place equally divided points on the arcs
e the new points to create diagonals
5.Coloured representation of the frame
6.Generate frame in Revit in ordered way
Computational Design
meets Structural Analysis
1.Import external geometries defined in a DWG drawing
2a. Generate points at the reference lines as base for the arcs, and connect the with lines
2b. Create a point for the arc creation, based on the middle of the line
2c. Create the arc based on the three reference points
2d. Discretize the arcs in polylines and create diagonals based on the arc division points
3.Create the geometrical model in Robot Structural Analyis
4.Define loads and boundary conditions for the model
5.Analyze and review the results
