modified_parametric finktruss-bridge

hallo everybody,

I made a parametric finktruss-bridge with grasshopper.(File 'Finktruss.3dm' and 'Finktruss.ghx')

(I also put some informations in this 3dm file so that you will see the problem.

I use command 'divide' and 'shift' to creat the lines through some points along the baseline.

But it seems donsent work perfectly.

It would be very nice if anyone could tell me how can I solve this problem.

thx.

Hi Frank,

I think there's an issue with rar attachments, I couldn't open it.

I haven't explicitly enabled fink trusses (yet) but I've covered a lot of others. The fink is an interesting case (with two curves for the top chord unless you use a polyline), but you might be interested in this demonstration : http://www.grasshopper3d.com/video/grasshopper-trusses

Please get in touch if you want to learn more,

Cheers,

Jon

Hi Frank,

Because of Ning I'm unable to download the file I think it has major problems with the rar extension. If you zip it it should work ok.

In the mean time, I just posted this in another thread Click here. Which shows some common ways of reducing the list. If your data structure is more tree like then you can do the same methods on a Para Viewer (address list of branches) and then use the specific tree branch component.

You could generate the points along the curve using the evaluate length component, with the length factor is normalized boolean set to false. This gives a point at a given length of a curve. The series of lengths you supply are a list of partial results from a Mass addition component. Hopefully what I've laid out below will give you some kind of idea as to where to go with your solution.
