still failling with easy stuff

i just tried to perform something i saw in a video (sorry i don't have the link)
anyway, will be easy to follow my steps and to see the problem.
i start with a plane
extract its points (4)
draw 2 triangles with those 4 points
offset
fillet
and make a planar surface.
THAT'S DONE.
then i want to use the same file to apply to a surface, and even i used the SubSurf (Isotrim), i can't get it applied correctly.
hopefully someone will easily see my mistake, and i thank you for your help.
Thanks,
Javier

Hi Javier,

The problem you are faced with is you are only taking the first four values in a flattened list and therefore only applying your definition to one of the 9 sub surface. In order for you to get it to work you have to create a series of numbers to generate every 4th surface point. After the flattened list you need to add an extra branch for every data item by using the graft component. Switch on fancy wires from the view menu and you will be able to see the output as either single, double or dashed wires which gives you an indication as to what the data structure is.

Best regards,
Danny

Hola Javier,

He rehecho tu definición porque se me petaba el rhino cuando modificaba la tuya. Tienes unos flatten en los List Item que no deberían estar y al quitarlos se me congela. El caso es que al rehacer no he tenido problemas.

Los sliders son absolutos así que ten en cuenta que si haces muchas divisiones en U y V las medidas del fillet y de la distancia tienen que estar en relación a esas divisiones.

Por otro lado, hay otra definición para hacer esto mismo (paneling, al fin y al cabo) en la pág 79 del Grasshopper Primer, y ahora encima tenemos edición en español. Además en los archivos de apoyo tienes la definición hecha.

Espero haberte ayudado. Un saludo.
