This video has been made for the final Innochain Exhibition and presents a series of modelling experiments that have been conducted during my PhD thesis. From 0:20 to 0:50 : Interactive modelling for free-form timber structures. The library GraphViz…



  • there is a missing link in the digital chain between the construction idea and its fabrication, which was – and still is – inhibiting an efficient digital process.
  • our business model is mainly based on our enthusiasm for great buildings and a large portion of laziness
  • In non-standard, complex-geometry, pre-fabrication projects many questions need to be asked (and answered) at an earlier planning stage.
  • Design-to-Production provided a full digital-planning, 3D-models and fabrication data.
  • is about the smart setup of a project workflow.
  • impossible without digital pre-fabrication
  • Therefore, the fabricator needed a precise digital fabrication model, and at 1,800 bespoke components it was also rather obvious that nobody wanted to model them by hand. So, a parametric model was created, that generated all the intricate details automatically
  • we use one of the cheapest 3D modelling programs available on the market (Rhino from McNeel), and we exploit it by extending its abilities with our own tools and plugins we program, often project-specific.
  • “design patterns”
  • large scale parametric digital 3D models
  • We are plugging into the other project partners’ workflows and provide digital information in a way they can use without additional effort


  • Can BIM help for more conventional demolition projects?
  • the model we created from the point cloud allows us to determine section sizes, and plan the demolition sequence – crucial when there are big machines snipping through the trusses, and removing the wrong section too early might affect the structure’s stability


  • Since the timeline for Concept design phase is generally short, designers tend to use tools that are better suited to design exploration than design interrogation. It also makes sense, in Concept design phase, to keep the model ‘nimble’ since designers may not yet have the ‘information’ part of BIM
  • BIM models are by their very nature large complex datasets. As a result, allowing users to parametrically explore such models may severely reduce the latency and robustness of the system
  • Therefore, it is better for designers to create a federated BIM model using Computational BIM workflows rather than struggle with the limitations of any one BIM system
  • categorized Computational BIM workflows as either Tightly Coupled (Fully compatible) or Loosely Coupled (Fully interoperable)


  • Computational BIM workflows that are currently in use in the AEC Industry.
  • Geometry Gym


    A complicated workflow, but allows for greater parametric control over IFC properties.

  • VisualARQ


    An easy-to-use Rhino to IFC plugin.

  • Hummingbird


    Works well for simple projects with repetitive elements.

  • Grevit


    A promising plugin for Rhino/GH & SketchUP to Revit interoperability

  • Rhynamo & Mantis Shrimp


    One of the better Rhino-Revit interoperability plugins

  • Flux


    The future of software interoperability and collaboration

  • GH-ARCHICAD Live Connection & Rhino-GDL Converter.


    The best-in-class Computational BIM workflow ever

  • create a federated BIM model using Computational BIM workflows rather than struggle with the limitations of any one BIM system


.@enneadarch what's a *computational #BIM specialist*? @archinate explains https://t.co/YjCeIAzoWu & MIT's… https://t.co/m5RiWipb6X

  • what a ‘computational design’ position actually means in a business setting
  • specializing in geometric complexity
  • automating project design studies and creating variations
  • problem-solving methodology
  • A computational designer should be able to describe the design problems they have encountered projects and how they developed the computational workflow to aid in their resolution
  • Like any designer, a computational designer should be able to reflect on the value of their methodology and explain how their method produced more desirable results for the project and the team
  • computational design is not BIM. BIM is also not computational design
  • company to think about how a range of skillsets can be built up over time
  • the company could focus on hiring or partnering with an expert in the field.
  • they should be interested to learn about the design challenges specific to your firm and describe a computational vision that can help lead your business to the best possible solution
