algorithmic modeling for Rhino

Hey guys
I have been trying to make a definition that makes a dynamic facade like the one on the image


I startet just with one singele unit to try to make it work and then jummp into making all those diferetn pattern possible. so far my problem is that I cant make both joints move together. take a look of my definition and tell me if anybody can find a way to make ot work or improve it

you are moving the wrong thing. Lets say point C is the start of the line, and point D the end of the line (connected to pt B). B Needs to be a polar point about D...B needs to have an arc or circle which defines the motion of the joint...this arc must intersect the line between C and D and will give you point A...check out mechanical linkages...
reference a pt and try this...sorry its messy, I did it quickly...

this is what you are talking about? the definition add this but it was just hiden.
what do you mean with "B Needs to be a polar point about D" sorry about my ignorance
but I dont understand what do you mean with that.
please take a look of the definition your healp will be appreciated
did you look at the definition I posted?
I am going to check it out right now thanks for helping man!
Here is a little video that shows the movement of the mechanical linkage
but I need the point A to follow the point B
how do I this?

Luis Fraguada thanks so much I just saw you def (by the way I had to download the latest grasshopper) and try to undestand some new thing to me that you have in you def.
I will take a look of it later and try to understand how it works thanks so much though if I develop something better I will show you or maybe ask for your help again :P
take care good luck
Hola Francisco.

Espero que te ayude.
Saludos.

Creo que la primera def. te va a servir mas....puedes linkearla a una crv dibujada en rhino.
The point of speaking in english is that everybody can understand, use, ask or whatever without the need of a translator. This is a international forum, and it's both ways good to be understodd by everybody and understand everybody!

Should I write in catalan?
Have I been very rude or its just me?

I have to apologize, was a bad reaction, sorry. I've been claustered in my room for too long, lost in laberintic forests of fancy wires and every day more cool components...

:)
no et preocupis, és bo sortir a veure el sol de tant en tant ..... salutacions
