1 Analysis of freefrom curve and rhombus linkage generation

Curve2Linkage is a Grasshopper script that generates rhombus type scissor linkages on any 2D curves by calculating points, vectors, and planes on the curve. The initial concept of the rhombus scissor linkages was from Chuck Hoberman’s ‘Transformable Design Method’ lectures 2019.

Understanding linkage mechanism is essential to design transformable design. However, mathematical logic behind linkages often behaves as a barrier for some design major student. The Curve2Linkage documents mathematical reasoning behind the linkages and provides fabrication data that students in GSD or all over the world help them to understand linkages.
