[Plugin] Click2flip v1.0 20110928

You might find it useful to set the back face color to something more easily discernible. I use a green I'd never use in the model as a color/texture.

Yes - that's a generally good idea but since sometimes you have materials on the back side you need to go monochrome and back too see whats going on.. anyway since this plugin already exist - adding a label option will add great usability if possible..

great and simple tool, would be super-fab if able to flip curved faces as well!

...i thought combining the 2 bits of code above might do the trick:

1, click2flip
2, flip selection

the idea being that if i click on a curved face, i'm also selecting it and therefore running the 2nd script might reverse the whole curved face, say a cylinder. (ideally i thought it could be toggled by pressing an accelerator key) a fair bit beyond my christmas powers... surely possible though..?

        ph.do_pick(x,y)
        @face = ph.picked_face
        self.flipper() if @face
    end
  end
  def flipper()
    normal=@face.normal
    vector=@pt.vector_to(Sketchup.active_model.active_view.camera.eye)
    angle=normal.angle_between(vector)
    if angle > 90.degrees
      @face.reverse!
      UI.beep if @@BEEP
    end#if
  end
end#class

def self.flipBacks()
  model=Sketchup.active_model
  eye=model.active_view.camera.eye
  faces=[]
  Sketchup.active_model.selection.each{|e|faces << e if e.class==Sketchup;;Face}
  return nil unless faces[0]
  model.start_operation("Flip Selected Back Faces...")
  faces.each{|face|
    normal=face.normal
    vector=face.bounds.center.vector_to(eye)
    angle=normal.angle_between(vector)
    face.reverse! if angle > 90.degrees
  }
  model.commit_operation
end

EDIT: actually just noticed the second script only flips half a cylinder (the side to the screen), the back remains undone.
