How to place 'Groups' or 'Components' rotated ?

[renderiza]

Hi,

I want to expand my Canvas plugin to add rotation values when inserting groups or Components.

Problem is that with the code below the object is inserted using Z axis located on (0,0,0) coordinates and I want to rotate the object using cursor z axis coordinates instead.

I know how to position the position of the vector when I want to raytest but not this...Please Help!

def activate
  @@sel = Sketchup.active_model.selection[0] ;
  @@ents = Sketchup.active_model.active_entities ;
end #def



def onLButtonDown(flags,x,y,view)

 ip1 = view.inputpoint x,y ;
 @point = ip1.position ;

 add_object(@point) ;

end #def



def add_object(point)
 vector = Geom;;Vector3d.new 0,0,1  #Want the position to be on cursor
 t = Geom;;Transformation.new @point, vector, 45.degrees

 if @@sel.is_a? Sketchup;;ComponentInstance
   @@ents.add_instance(@@sel.definition,t) ;
 end

 if @@sel.is_a? Sketchup;;Group
   defn = @@sel.entities.parent ;
   @@ents.add_instance(defn, t) ;
 end	

end #def
