And you gathered all those panels into a single panel?
I am confused because otherwise you will have to have few excel files, imported into Midas civil?

@djordje: I added Panels after some key points like end points of beams, hangers, etc. to get the position in vectors. Since grasshopper and Excel can both auto-update data, this works pretty well : )

Thank you for the reply Peter.

That Panel from which you exported the data to excel format - it was a panel going out of the final "geometry" parameter, at the end of the definition? Or?

i love it..can you share me this definition..I can research it further..thank you so much.

@djordje: I didn't export the whole bridge model, because the grasshopper model needs some translation to incorporate analytic capabilities, and I didn't know how to do this step automatically. To analyse the structure using beam and link elements, I only needed some points and lines from the grasshopper model, and some additional information such as materials and loads. I used Excel to automate the process as much as possible, but I still edited the FEA model manually after it was created with the help of Excel.

The exporting part in grasshopper is easy: right-click on a Panel and you will see "Stream Contents" and "Stream Destination", and that is where I started.

Thank you for the reply Peter.
But I am not sure I understood you about the exporting part - you exported your Rhino/Grasshopper as some sort of node model (.dwg, .dxf ?) and the imported it into the Midas Civil?

Thanks, djordje! I used Midas Civil for the structural analysis. I used a bunch of text tags in grasshopper to export positional data to Excel forms. I wrote some equations and macros to manipulate the data and then paste them into Madas Civil as node forms and element forms.

I love the curved shaped and the dissymmetry of arches cables. Great work!!!

By the way, which application did you use for the structural analysis? And in what format did you export the model from Rhino? .3ds?
