Tridimensional truss parametrically designed

This tridimensional truss has been made through parameters that can be reconfigured automatically if we change the initial surface.

In other words, I started making a 3D surface, and after editing its points on the space, it is possible to parametrise a truss with Grasshopper.

The process is quite easy to understand. Firstly we have to divide the surface into pieces, after that, we have to extract the isoparametric subsets of this surface. With the Deconstruct Brep, we will get all the vertices, edges and vertices we need to build lines and curves and finally get a tridimensional truss.

To take control of the height of the truss, it is necessary the Evaluate Surface and the  components, as you will see in the image below.

As a structural engineer, my main concern is to verify the stability of the structure, so I need other software which I can solve trusses, like Robot Structural Analysis. Baking the parametric design into lines I could export them and import into RSA without many problems.

The best think about way to design structures is that it is really easy to modify the main surface, and after that we can export the frame to a structural software. We don’t need to rebuild all the frames, node by node, frame by frame.
