@designerbursa what do you mean?

[designerbursa]

@rv1974 I developed the code for pasting on all selected surfaces at once, it would be useful for everyone if it is updated in this way.

@designerbursa
I might be missing something but currently I can do it without any plugin

[designerbursa]

@rv1974 If you can paste without extensions, I really congratulate you...

@designerbursa

@rv1974 I am using Sketchup 2021 version

[designerbursa]

@designerbursa ```

module GlueComponentsToFaces
  extend self

  def glue_components_to_faces
    model = Sketchup.active_model
    selection = model.selection

    if selection.empty?
      return UI.messagebox("Error: No selection! Please select faces and components.")
    end

    faces = selection.grep(Sketchup::Face)
    components = selection.grep(Sketchup::ComponentInstance)

    if faces.empty? || components.empty?
      return UI.messagebox("Error: Select faces and components!")
    end

    model.start_operation("Glue Components to Faces", true)

    begin
      components.each do |component|
        closest_face = find_closest_aligned_face(component, faces)
        component.glued_to = closest_face if closest_face
      end
    rescue => e
      UI.messagebox("An error occurred: #{e.message}")
    ensure
      model.commit_operation
    end
  end

  def find_closest_aligned_face(component, faces)
    component_normal = component.transformation.zaxis
    closest_face = faces.min_by { |face| face.normal.angle_between(component_normal) }
    closest_face
  end
end

# Adding a menu item for ease of use in SketchUp
if not file_loaded?(__FILE__)
  UI.menu("Plugins").add_item("Glue Components to Faces") {
    GlueComponentsToFaces.glue_components_to_faces
  }
  file_loaded(__FILE__)
end

### I haven't tested it on the 2024 version but you can try this, maybe it will work. It works smoothly on my 2021 version

@designerbursa I took a closer look.. your version is indeed more advanced and user friendly, many thanks!
P.S. you can cut and paste in place multiple and un-glued components in any SU version to get the same positive result, but your script is less laborious indeed.
