I’d like to share a recent case where Grasshopper really helped streamline a small but tricky project.
The task was to design a dormer for an existing house. At the start, nothing was fully defined:
-Dimensions were not precise.
-Orthogonality of the existing roof was compromised.
-Regulations were from another country, not fully clear.
To handle all this uncertainty, I set up a parametric workflow in Rhino + Grasshopper:
-Geometry controlled via a guide curve and sliders.
-Angles, joints, and timber connections resolved parametrically.
-Fabrication files exported directly from the definition.
This allowed quick iterations as regulations and client decisions evolved, without redrawing from scratch. It also helped avoid errors and reduced time/cost on the fabrication side.
Here are some images of the process and results:
Curious to hear:
How would you approach this kind of “uncertain geometry + unclear regulation” scenario?
Any ideas to make the workflow even more efficient?
