What is a .CUS file?
The .CUS file extension refers to an AutoCAD Custom Dictionary File. This type of file is associated with AutoCAD, a software application used primarily for creating detailed architectural designs and documentation. The .CUS file contains a dictionary, which is essentially a list of words. These words are stored in a simple text format, with each word separated by a line break.
The main purpose of a .CUS file is to help users manage spelling within AutoCAD projects. It stores a list of words that are exceptions to the usual spelling rules. This means that when the AutoCAD spell checker runs, it won't flag these words as mistakes. This is particularly useful for including specialized terms, such as company names or industry-specific acronyms, that are not found in a standard dictionary.
You can open a .CUS file with several programs. The primary program is Autodesk AutoCAD 2023, which is specifically designed for handling such files as it directly integrates with the software’s spell checking function. However, since .CUS files are saved in plain text format, they can also be opened and edited with basic text editing tools. These include Microsoft Notepad and Microsoft WordPad, which are typically included with most operating systems. Additionally, any other text editor capable of reading ASCII text files can be used to view and modify .CUS files. This flexibility allows users to easily edit the list of custom words directly, using their preferred text editing software.
