Hi guys,
You know, because SU is face based 3d program solidtools sucks sometimes.
But what about Spaceclaim, it is awsome solid 3d program and besides can save the objects as Sketchup .skp files.

If you can't do something, think about it...

Not: this is not advertisement just favor.

I think eventhough the title has "Solved" the last solution is missing

Here is one of them.

model = Sketchup.active_model
ent = model.entities
sel = model.selection

defn = Sketchup.active_model.definitions

def onMouseMove(flags, x, y, view)
  return nil if not @instance ### only works when instance is set
  @ip.pick(view, x, y)
  if @ip != @ip1
    view.invalidate if( @ip.display? or @ip1.display? )
    @ip1.copy!(@ip)
    view.tooltip=@ip1.tooltip
    @instance.transform!(Geom;;Transformation.new(@ip1.position))
  end
end

def onLButtonDown(flags, x, y, view)
  return nil if not @instance
  @ip1.pick(view, x, y)
  if @ip1.valid?
    @instance.transform!(Geom;;Transformation.new(@ip1.position))
    @instance=nil ### un-sets instance
  end
end

lastdefn = defn[0] # ! I had just one definition in my component definition list therefor defn[0] worked well for me
model.place_component( lastdefn , false )
