Reverse engeneer mesh from csv, Dutch Dynamo Day

1

Today we had a wonderful sunny day in Delft in the Netherlands with The Bad Monkeys :slight_smile:
Many thanks to Havard Vasshaug, Andreas Dieckman, Julien Benoit and Dieter Vermeulen.

One of the questions still unsolved (time issue) was to recreate a mesh from csv/xls.
https://dl.dropboxusercontent.com/u/87228844/Mexico_GeheleMesh_Pts.csv

This file is the roof for the new Mexico City airport, in its early stages, by Norman Foster, which gave me the inspiration to give Dynamo a go because of its awsomeness.
Here is a link to the video https://vimeo.com/147686009 so you can see why i turned to Dynamo :slight_smile:

Since this is a big file (45min to import), im askin for the principle of recreating a mesh from points, a hexagon with some hexagons around it would do the trick.

Had a wonderful day today.
Regards,
Marcel

You have two options:

1 Do what F+P did…and use Grasshopper

or

2 Write a simple loop function with inputs to control the start and end, then iterate through the excel data to create the points. You can now limit the load on your memory and produce the model in pieces. If you then array adaptive components over the point grid, the final step is to work out how to link the pieces back into one model without hitting the same performance issues.

HI
I quickly tried something that may actually work but is really dirty :smiley:
I only tried it on a small part of the CSV
I am creating a topography mesh(i am sure that part could be avoided), getting the surfaces and filtering the aditional surfaces by area.
This was the first thing to pop up in my mind :slight_smile:
