Error when void shape?????????

ELEKVN

   I want to creat one shape and void it.
  I could creat shape by blow code
        
        ;*************************
        mypath = axlPathStart( list(-3200.000:5812.000))
        mypath = axlPathLine( mypath, 0.0, -3200.000:5020.000)
        mypath = axlPathLine( mypath, 0.0, -4016.000:5020.000)
        mypath = axlPathLine( mypath, 0.0, -4016.000:5812.000)
        mypath = axlPathLine( mypath, 0.0, -3200.000:5812.000)
        myshape = axlDBCreateOpenShape( mypath, t,"etch/top", "GND")
        axlDBCreateCloseShape( myshape)
        ;*****************************
 But I could't void this shape by below code:
         ;******************************
        axlSetFindFilter(?enabled (list "noall" "Shapes" "Voids") ?onButtons (list "noall" "Shapes" "Voids"))
        while((axlSelect)
        myshape = axlGetSelSet()
            foreach(myshapes myshape
            myvoidpath = axlPathStart( list(-3519.000:5586.000))
            myvoidpath = axlPathLine( myvoidpath, 0.0, -3519.000:5259.000)
            myvoidpath = axlPathLine( myvoidpath, 0.0, -3742.000:5259.000)
            myvoidpath = axlPathLine( myvoidpath, 0.0, -3742.000:5586.000)
            myvoidpath = axlPathLine( myvoidpath, 0.0, -3519.000:5586.000)
            axlDBCreateVoid(myshapes, myvoidpath)
            axlDBCreateCloseShape( myshapes)
            )
        ;****************************
I see warning in Allegro screen:

    E- Unfilled shape can not contain voids
    E- Database object is not a shape.
    
Can you  help me correct it.


Thank you.

  •  By the way, I want to create a shape with void by text using axlText2Lines as following code:

     

     foreach(text AllTextsInDesign

                lines = axlText2Lines(text)

                ; flatten list

                flattened = foreach(mapcan x lines x)

                text_bBox = text->bBox

                ;enlarge bBox

                shape_box = list(axlMXYSub(car(text_bBox), add_shape_value) axlMXYAdd(lastelem(text_bBox), add_shape_value))

                create_shape = axlDBCreateRectangle(shape_box, t, layer_check, nil , nil)

                shape_ID = car(create_shape)

                foreach(path flattened

                            ; may return multiple polys

                            polys = axlPolyFromDB(path ?endCapType 'ROUND ?line2poly t)

                            ; create shapes in database

                            foreach(poly polys

                                        axlDBCreateVoid(shape_ID poly)

                                        ;shape_void = axlDBCreateShape(poly t layer_check nil nil)

                            );end foreach

                );end foreach

    );end foreach

     And the result is nothing happens(no voids created), please tell me how to repair code.(My allegro = 16.6)

     Thanks.
