### **Overview**

The Wall Duct or Pipe function creates a dimension between a selected wall and a duct or pipe and adds the DN parameter from the selected pipe to the dimension label. To use this function, you should first select the wall and then the pipe/duct element. This can help you accurately measure and document the distance between these two elements in your project.
