Dividing the surface into primitive rectangles

Grasshopper
1

Hi all. Please help me solve the following problem. There is a trim surface. I need to divide it into primitive rectangles to further build a fully rectangular mesh.
I would like to solve this problem with built-in components, but if it can not do without plugins, then let it be through plugins.
The numbering is an example of what I want to get. I present two variants of the final result, but I will be satisfied with the one I can get the fastest.

Hi,

Here is one idea but specific to your case (only vertical divisions).

There are more complex solutions here.

Thank you, your solution is very compact and you can say what you need. I will try to understand how it works, because in general I understood that I needed to use control points, but I didn’t quite understand how it could be done.
The link to the other post is :exploding_head:, I’ll have to figure it out this weekend :grin:.

I slightly modified your solution to my needs. Maybe if you have time you will find a way to simplify my script, if possible. I will shortly describe what I did:

  1. I ideally wanted to get rid of these lines (pic) - I didn’t need to divide the plate at this point. To do that, I first trimmed the lines along the surface boundary. Then I removed the lines that duplicate the contour of the surface itself. And at the end I filtered the endpoints to belong to the points of the surface itself.
  2. I needed to add a horizontal division as well - to do that, I corrected part of your script
