1 Reply

I have a custom component that can work on either 2 or 3 lists of curves as inputs, each of which is set up as a separate input parameter. However, it's not possible to set default values for Curve…Continue

For anyone looking at classic double layer gridshells (Mannheim, Weald and Downland etc) this set of components will be useful. There are tools to create centreline geometry (for analysis etc), lath…Continue

Latest version of Gridshell Components

I've cleaned up Gridshell Components and put together a few example GH files to get started. The inputs and outputs have been rationalised to speed up the modelling process.

 

I've also added an 'Unroll Curves' component which measures the geodesic curvature of a curve on a surface and produces the 2D 'unrolled' curve. Geodesic curves (e.g. those produced with the Shortpath command) unroll to straight lines. It is now possible to generate fabrication patterns for any…
