4 Point Surface from Point Lists

Grasshopper
1

Hello,

I am trying to simplify some surfaces, so that I can use them in a calculation, and wanted to automate the process a little bit. I have the outline curves, which I divide in an x amount of times, and want to use the points I get to build simple 4 point surfaces. However once I get the list of points, I don’t know exactly how to do what I want.

The problem for me comes from wanting to use some of the points 2 times, so that I can get touching edges.

Hi,

Two solutions attached. One with Polyline + Loft (straight). Simple but you don’t get you output surfaces sorted out.

Or a more convoluted one based on Relative Item. The output tree is nicely sorted by column/row.

Hello,

so the previous script worked wonders and saved me a ton of work, but now I am faced with another dilemma. I made a script that simplifies a geometry and that works on a single geometry, but if I add multiple, it breaks. I know it has to do with data trees, but at the moment am unable to figure it out.

Can someone help? Below the script with internalised data

Thank you,
Hristo

Hi,

Because you are dealing with several Breps, your tree structure has an extra level that needs to be added in the offsets of the Relative Item components.

I also took the liberty of cleaning your cleaning procedure :smiley:
