Summary of Exploring Eagle CAD ULPs #2 – ‘Unrouted.ULP’ Zoom To The Last Left unrouted Wire
This article introduces "Unrouted.ULP," a User Language Program for Eagle CAD designed to locate unrouted wires in large boards. Unlike manual searching, this tool automatically zooms to the first remaining air wire, enhancing efficiency when using the ratsnest feature in the layout editor.
Parts used in the Unrouted ULP Project:
- Eagle CAD software
- Unrouted.ULP file by Daniel Mack
- Ratsnest feature in layout editor
Welcome to the second post of the “Exploring Eagle CAD ULPs” series. Every week we will publish a new post about one useful ULP in Eagle CAD.
“ULP” User Language Program is a plain text file which is written in a C-like syntax and can be used to access the EAGLE data structures and to create a wide variety of output files. You can consider it like a plug-in for Eagle.

In this post we will discover “Unrouted.ULP” by Daniel Mack. The job of this ULP is to zoom to the first unrouted wire in the board editor. This might be helpful when searching for tiny leftover air wires especially in big boards.
When we use ‘ratsnest in layout editor, a result with remaining airwires is shown in the bottom of the editor. Sometimes airwires are not visible to our eyes and need a lot of searching.
