The Sun Is a Zoning Rule You Can Compute: Knowles' Envelope and Zürich's Three-Hour Shadow
Ralph Knowles' solar envelope and Zürich's ABV § 30 shadow rule share one inequality. Carve the hull, test the tower, loft it in Grasshopper + Rhino.
Pull, Don't Draw: The Control Polygon Under Every Rhino Curve
How one idea, cutting each leg of a control polygon at the same ratio, became the Bézier curve and the NURBS geometry behind every Rhino control point.
Hang it, then flip it: the sketch that does what Gaudí did with lead sacks
A cord can only pull, so a flipped hanging net only pushes. Follow Gaudí, Frei Otto and ETH's Block Research Group, then reseed the sketch in your browser.
Dynamic Relaxation: How a 1965 Algorithm Lets Kangaroo Find the Shape Where Motion Stops
How A. S. Day's 1965 dynamic relaxation method finds equilibrium shapes, from Barnes' kinetic damping and Downland gridshell to Kangaroo in Grasshopper.
A Wall Is a List: Coding the Bond, the Overlap Rule and KCAP's Strasbourg Tower
A wall is a list: code the Eurocode 6 overlap rule, see stack bond fail and a 16 % offset lock, and follow it to the KCAP tower in Strasbourg.
Chair44: a cube missing one corner that fills space and never repeats
A seven-cube chair with three colours of marks fills space but never repeats. How Chair44's 8-page proof works, and why one part needs one mould.
One shape, no repeat — and the bill for building it
How the hat monotile quietly needs two moulds, why the chiral Spectre needs one, and the two debugging lessons behind PAZ's verified tiling sketch.
One Casting, No Joints: The Geometry Under the Giga Press
How single-piece megacasting eliminates joints: the topology, the clamping-force maths, and what part consolidation teaches an AEC studio.
BIM Interoperability: the building is the hand-off, not the model
Why two ISO 16739-compliant IFC exports can describe two different buildings — and how to police the seam with ifcopenshell, ISO 19650 and openBIM discipline.
Digital Twin: the model that never stops listening
From NASA's 2010 definition to bridge and BIM twins — what a digital twin really is, why it holds, and the one scalar your office must name before calling it one.
