CityWave: Rhino → ETABS + Revit Workflow

Timo developed a workflow connecting Rhino geometry to ETABS and Revit models for CityWave in Milan. This allowed the engineering disciplines to keep pace with the architects’ design changes.

Work by Timo Harboe while employed at Bjarke Ingels Group.

The Work

CityWave’s complex geometry meant that changing the roof or floor heights also changed the slabs, edges, and columns. Timo linked these elements in Rhino so they could be updated together, then transferred directly into ETABS and Revit for structural analysis and modelling.

He also built parametric analysis models of the large canopy. This let the architects keep refining the design close to the deadline while the engineering team could quickly update its models.
