Building Your Own Urban Tool Kit
Why Conduct Urban Design in a BIM Application?
Design inside the "software comfort zone" of the architect
Utilize parametric & analytical capabilities of BIM software
BIM to CIM is only a matter of time anyway
Project Goals
Component-based workflow
Rapid large-scale distribution of components
Tabular reports
Visual filtering
Exploration of design alternatives
Chosen Platform:
Autodesk Revit
Components
The body and mind of the Urban Tool Kit
Define the methods and structures of the solution
Approach
Zweckentfremdung:
To divert something from its original use
Model city blocks as mass surfaces
Subdivide city blocks into parcel grid
Populate parcel grid with building components
Modeling
Workflow
Patterning
Manual alterations
Patterning with Divide & Repeat
Reactor patterns with context-aware adaptive components
Analysis
Tabular reports
Filtered views
Further analysis
Rule-based
Manual
Components
Dynamo
Autodesk's open source
visual programming environment
for the Revit platform
Example #1:
Two-Point Reactor
Drive the heights of buildings by determining their proximity to specified reference points in the project
Example #2:
Pattern Recognition
Drive the building component types by processing an image with a placement pattern
