Files with .cus extension are AutoCAD custom dictionary files. The .cus file format is developed by Autodesk for use with AutoCAD on Windows. Although mainly used by AutoCAD, 2 other programs can also open .cus files. To learn more about .cus files and the AutoCAD software, check Autodesk’s website.
A .cus file contains custom dictionary for AutoCAD, a CAD and CAM software. These files are likely not meant to be directly accessed by users. It is unlikely .cus files can be converted to other formats.
.Cus files are ASCII text files that can be viewed and edited with a text editor. They fall into the general category of settings files. Over 1,300 different file types belong to the settings files group.
Problems opening .cus files usually happen when they become incorrectly associated with the wrong program. To open a .cus file, right-click or long-press it, then use the “Open with” menu to select AutoCAD or another compatible application. You can also display .cus files directly in a browser window by dragging and dropping onto the window.
