relaxation form finding 2

Second version of the form finding tool in processing. There are a few improvements to version one of the sketch:
  • triangulated point grid for more stability
  • points can move in x and z-direction now (only as long, as the structure is still buildable)
  • a better exporter, to wind up the bended girders. The sketch saves a pdf file for prototyping eg. on cnc laser cutting machines
Like in the first version of the sketch, the girder depth is calculated by the stress values of each point in the grid. While designing the form with the tool, you can see these values displayed in the stress map (take a look at the video above for a little demonstration).
