Combining several polygons

Question

with my python script I create a cross-section out of several polygons. They are different surfaces with different material parameter. My problem is that I have severall polygons which are very close to each other but not connected. For further calculations I need to connect these polygons. I don´t want to have one big polygon. I just want to have the small gaps closed between the different polygons and they should stay still seperated by bounds.

Somehow I tried a lot but at the end everything got to a big single polygon.

Here a code snippet: I create so called "sections" with the section_multiplane and out of this i create the polygons with the shapely polygon tool. And these polygons, in this case just as example, are very close to each other and I just want to close the gap between these two.

sections = mesh_kr.section_multiplane(plane_origin=mesh_kr.bounds[0], 
                                   plane_normal=[1,0,0], 
                                   heights=x_levels)

sections_belag = mesh_belag.section_multiplane(plane_origin=mesh_kr.bounds[0], 
                                   plane_normal=[1,0,0], 
                                   heights=x_levels)

poly_kr = sections[20].polygons_full[0]
poly_belag = sections_belag[20].polygons_full[0]

Need to edit I can easily generate vertices of the polygons. So maybe there is a way to combine the vertices?

Answer 1

sorry for elaborating not correctly. i added 2 pictures to this answer here. As you can see in the zoomed picture, there is a gap between the two meshes. And I´m looking for something that this gap gets closed, by connecting the two meshes together. But the goal is that the meshes will stay as seperated meshes.
