I am trying to import a csv file into blender, using the sverchok addon, and use one of the fields of the csv file to create geometry.

Here is my csv file: https://drive.google.com/file/d/1YYlrie8CbP2eBErp90laizbZE9zvD9N2/view?usp=sharing

Blend file: https://drive.google.com/file/d/1vuHqgELdB9uGirzJZqjWDBiQbu8f9I4z/view?usp=sharing

The first field in this file, 'WKT' is the geometry data in Well-Known Text format. This geometry data is setup as such:

"MULTIPOLYGON (((286964.0223 5413712.8119,286957.0751 5413828.394,....)))" where:

  • MULTIPOLYGON = description of the type of geometry
  • 286964.0223 = x-coordinate of the first vertex
  • 5413712.8119 = y-coordinate of the first vertex
  • 286957.0751 = x-coordinate of the second vertex
  • 5413828.394 = y-coordinate of the second vertex

Essentially, the 'WKT' field is a list of vertex coordinates. I would like to use these coordinates to create geometry, but am having trouble getting sverchok to recognize the 'WKT' as a list. To make this field recognizable as a list I've tried:

  1. Removing the "MULTIPOLYGON " text
  2. Changing the parentheses to brackets

These changes, along with different node trees using the string tools, numpy array, and various list nodes have not produced any results.

How can I format/manipulate/process the 'WKT' field in my example file in order to create geometry through sverchok nodes?

Thanks,
