Hi @ROS_Expert, Section 2.3 showcases how to view the TF tree in PDF format. Section 2.4 showcases how to view the TF tree with `rqt`. Both sections are the same in the sense that their objective is to visualize the TF tree. The methods are different. So it is not an error. ---

I’m sorry, I’m having trouble understanding your post. Could you share a screenshot of what you mean? I don’t see the same content in Sections 2.3 and 2.4. I see different content: ![Screenshot from 2025-03-27 10-05-16](https://get-help.theconstruct.ai/uploads/default/original/2X/a/a389e6dbfbc5a28e89ec69ad6a74798dba4a0788.png) ![Screenshot from 2025-03-27 10-05-33](https://get-help.theconstruct.ai/uploads/default/original/2X/e/e31d4d0df817fd6decd49f74308a0481422d0d20.png) ---
