What is a .DRU file?
A .DRU file is a type of file specifically used in the context of designing printed circuit boards (PCBs). This file extension stands for EAGLE Design Rules, and it is associated with the software application called Autodesk EAGLE, formerly known as CadSoft EAGLE. Autodesk EAGLE is a popular tool among engineers and designers for creating detailed layouts for PCBs.
The content of a .DRU file includes a set of design rules or guidelines that help ensure the PCB design meets certain technical specifications and manufacturing standards. These rules cover various aspects of the PCB design, such as the thickness of the layers, the minimum distances between electronic components, the size and shape of the components and their pads, the types of masks used, and the clearance between different electrical paths to avoid short circuits.
These design rules are crucial because they help in automating the checking process during PCB design, ensuring that the board adheres to necessary specifications and can be manufactured without errors. This is particularly important in complex electronics where precision is critical.
To open a .DRU file, you will need to use Autodesk EAGLE. This software provides the necessary tools to view, edit, and apply the design rules contained in the .DRU file to a PCB project. Autodesk EAGLE is available for various operating systems, including Windows, macOS, and Linux. Once you have Autodesk EAGLE installed, you can open a .DRU file by launching the program, navigating to the file menu, and selecting the .DRU file you wish to open. This will load the design rules into your current PCB project or allow you to edit them as needed.
