Export with "pen" or "correct line weight"

Hi everyone. I need to export a “line axonometry” and my first solution was to use the “pen” view. so I changed the parameters for the thickness of the lines in "object weight line) to have them as thin as possible (the buildings are meshes and therefore for me it is necessary to display only the lines of edges and shilouette, otherwise the subdivision of the models would be visible) .

I exported both as “viewcapturetofile” with a resolution of 5000x3000 but the lines of the buildings are always too thick, those of the road being curves (in which the change of thickness works) are printed correctly.

The problem is precisely with the mesh lines.

I also tried to print in vector from the “print” function, the result for the thickness of the lines is ideal, but I don’t know why the lines are behind the meshes of the buildings… which makes everything unusable.
Below are the photos.

Thanks in advance.
