The fastest, easiest, most intuitive way to check your PCB design… before it goes to manufacturing



3D BRD Viewer is a free tool to visualize CadSoft EAGLE PCB Designs in 3D. You can drag your .brd file anywhere on this page and have a full 360 degree view of how your board will appear after assembly.

Gerber Analyzer opens PCB Gerber files in the browser and goes beyond plain layer viewing. It runs thermal, EMI and impedance simulation directly from the board data, so you can see where copper is likely to run hot, where EMI may be a problem, and whether controlled-impedance...

Copper is able to open any Eagle CAD file saved in the XML file format (Version 6 and above). Copper stores its own settings in another file stored along the .brd and .sch files generated by Eagle and syncs any changes made in Eagle.
