Hi,

On my Interactor PythonPart, I can create well my object but the preview doesn't work

Here my code :

...

    def on_preview_draw(self):
        """
        Handles the preview draw event
        """
        self.create_geometry(True)

...

    def process_mouse_msg(self, mouse_msg, pnt, msg_info):
        """
        Process the mouse message event

        Args:
            mouse_msg : the mouse message
            pnt       : the input point in view coordinates
            msg_info  : additional message info.

        Returns:
            True/False for success.
        """
        input_pnt = self.coord_input.GetInputPoint(mouse_msg, pnt, msg_info).GetPoint()

        if self.coord_input.IsMouseMove(mouse_msg):
            return True

        self.selected_pnts.append(input_pnt)

        if len(self.selected_pnts) == 1:
            self.create_geometry(False)
            self.reset_pnts()

        return True


    def create_geometry(self, is_preview):
        """
        Draw the preview

        Args:
            is_preview : True/False if preview mode.
        """
        self.axis = Geometry.AxisPlacement3D(Geometry.Point3D(),
                                             Geometry.Vector3D(1, 0, 0),
                                             Geometry.Vector3D(0, 0, 1)
                                             )
        self.placement_mat.SetTranslation(Geometry.Vector3D(self.selected_pnts[0]))

        self.geo = Geometry.BRep3D.CreateCuboid(self.axis, 1000, 1000, 1000)
        self.model_ele_list.append(BasisElements.ModelElement3D(self.com_prop, self.geo))

        if is_preview:
            BaseElements.DrawElementPreview(self.coord_input.GetInputViewDocument(),
                                            self.placement_mat,
                                            self.model_ele_list,
                                            False,
                                            None
                                            )

        else:
            self.create_pythonpart()

Where am I wrong ?

Best regards
