how to attach the tool with from compas_robots.viewer.scene.robotmodelobject import RobotModelObject? robot_object.attach_tool_model(tool_model) robot_object.draw_attached_meshes() robot_object.draw_visual(),Not effective

tool_model=...
robot_object: RobotModelObject = viewer.scene.add(model, show_lines=False, configuration=configuration)

Attach the tool

robot_object.attach_tool_model(tool_model)
robot_object.draw_attached_meshes()
robot_object.draw_visual()

Not effective？

Hello, I'm not sure I understand your issue.

Are you asking why there is the code pattern of using the Scene class?

There is no example illustrating how to use robot_object.attach_tool() and display it on the Viewer.screen below, nor how to change the joint and have the end follow the changes. The example below only displays the robot, but not the tool attached to the robotic arm. Could the official provide a corresponding example that displays the robotic arm and end claw on the Viewer, without necessarily using ROS or Rhino for display.

Can you provide an example related to attach_tool and demonstrate how to display and update joint changes in the Viewer, ensuring that the tool at the end follows the changes, without utilizing ROS or other CAD environments。Thankyou very much。

programe:Only Robot is displayed below。
