Troubleshooting Problems Opening PC3 Files

Frequent PC3 Opening Issues

Autodesk AutoCAD Disappeared

You attempt to load your PC3 file and get an error such as "%%os%% Can't Open The PC3 File Extension". Usually, this is because you do not have Autodesk AutoCAD for %%os%% installed. Your operating system cannot associate your PC3 with Autodesk AutoCAD, so double-clicking the file won't work.

Tip: If you know of another program that can open your PC3 file, you can try opening it by selecting the application from the programs listed.

Wrong Version of Autodesk AutoCAD is Installed

Your AutoCAD Plotter Configuration File file is incompatible with Autodesk AutoCAD because you might have the wrong version installed. Download the latest Autodesk AutoCAD version from the Autodesk, Inc. website to ensure you have the correct one installed. This issue mainly occurs when your AutoCAD Plotter Configuration File file was created by a newer version of Autodesk AutoCAD than you have on your PC.

Tip: Right-clicking on your PC3, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

Primarily, problems experienced when opening PC3 files are due to having the incorrect version of Autodesk AutoCAD installed on your computer.
