problem with extrude projected curves to point

The data from the Project component is on multiple branches so therefore Each projected curve will match to every Evaluated Point. To rectify this the easiest thing to do is to flatten the input stream either with the Flatten Component or the input context menu Flatten option. The harder way to sort this is to use the pathmapper component to collapse the items on to the same branch something along the lines: {A;B;C}(i) --> {A;B}

Oh!

Thank you. Flatten component works!

Hi,

i am also new in the grasshopper world and doing the same tutorial as you did:Generative algorithms, from Zubin Khabazi, chapter5 column example. Can you tell me where you connect the Flatten Component?

Kindly

Marco

Using the attached image from the original post: Clip.jpg as a reference either Right click on the B Input to the Extrude Component and select Flatten from the context menu (version 0.8.xxxx) or Use the Flatten Component from the Sets>Tree panel of the Ribbon and feed output C from the Project Component into it and the flatten output in to B of Extrude. If you have Fancy Wires option enabled (View Menu) you will see the Wire change from a double dashed line to a double line.

Hi Danny,

that's really confusing me, I did like you said,... with no results at all. Maby is some else wrong. May i send you my files? Maybe you can check these files out?

Thank you anyway

Marco

Ah I see. Your problem is not the same as Gh has moved on a bit more. The output of the intersection component Project is now outputting every curve where there are multiples on to their own branches. But because some only have one curve in a "column" its not adding an extra branch.

 

To fix this you can Either flatten both inputs to the Extrude component or use the path mapper to put all the curves in each "column" on the same branch.
