Wow that is incredibly interesting. I’ve been meaning to make a move to c# and this is a fascinating case study. Thanks so much for in input!
See there I put the sript
It is classical Catmull Clark subdivision
Made this once to complete Colombo, Sri Lanka, where OSM had no data (green=OSM, red=script)
Rectangles were rotated to the nearest street, scaled, random reduced and culled if the proportions are over 4x1.
Following a part of the script. It requires Anemone.

Such an elegant solution! and beautiful results too.
There’s also this old thread that might be relevant:

Here a version with tileable subdivision. The same logic as previous, I add some mesh output so could be used to make a single mesh or a big tile.

Continuing to play with the subdivision script and mesh output, here on a torus.

Hey Laurent,t thanks for sharing this that script looks amazing, but when I load it I get the following error message:
- Error (CS1061): ‘Rhino.Geometry.Mesh’ does not contain a definition for ‘RebuildNormals’ and no extension method ‘RebuildNormals’ accepting a first argument of type ‘Rhino.Geometry.Mesh’ could be found (are you missing a using directive or an assembly reference?) (line 204)
do you know what this might refer to?
Hello
It is v6 command. I think you use rhinov5
True. Thanks for the reply
The function could be replaced by mesh.faces.compute normals then normals.compute normals … Or something like that.

Mesh.Normals.ComputeNormals() for the vertex normals and Mesh.FaceNormals.ComputeFaceNormals() for the face normals respectively .

Thank, not easy to answer correctly with a phone. I just think we must begin by normals of face then vertex.

this is pretty interesting! is it possible to change the rectangular curve input ?

Great work
Was this illustration used for a Master plan presentation of sorts ?
Laurent, this is an awesome script, thanks for sharing. What if I already have a defined set of rectangle sizes and a defined bounding rectangle. How would I go about packing them? I’m working on a little fabrication project and I want to lay out a set of rectangular parts on a large sheet to optimize material.
Seems to be a job for OpenNest! 
This is great. Thank you so much.
