algorithmic modeling for Rhino

Check if a surface or polyline is inside a closed curve

I have a group of surfaces/polylines and I want to select those that are inside a closed polyline and select them.

In the picture, I have this case, where I want to organise the buildings to their corresponding squares . so I want to select and group those who are in the same square (for example the black ones )

Isn't that the same problem discussed here?

Hi Dimitris,

- calculate area centroids of building surfaces,

- test area centroid + squares with Containment Ex,

- connecting relationship output to S input in member index component,

- set 2 (inside) in member to search input,

- use indices of member output as index in list item component, 

HTH
