Autodesk Custom Workspace Format is supported by 1 operating systems. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. The main program that supports this format is AutoCAD. This was created by Autodesk, Inc.. There are also 1 alternative programs to handle the CUI file. You can use 3ds Max in case AutoCAD cannot be used.

How to open CUI file?

The most common problem when using Autodesk Custom Workspace Format is that a specific CUI is not associated with the program. This causes the file CUI to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the CUI file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install AutoCAD

In this case, you should first verify that the AutoCAD application is installed on the computer. The easiest method is to use the system search engine by entering the program name AutoCAD in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open CUI files.

Step 2. Create association of AutoCAD with CUI files

However, it may happen that the application itself does not cause the CUI file to open in the AutoCAD application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the AutoCAD application as the default for handling the CUI file.

Step 3. Update AutoCAD to the latest version

If, however, after binding AutoCAD with Autodesk Custom Workspace Format there were still problems, you should update the program to the latest version. In this case, use the Autodesk, Inc. website or update the program from the application.

Step 4. Check for the following problems with the CUI file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to CUI files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file CUI or the program directory. Sometimes virus-infected CUI files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the CUI files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair CUI file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Autodesk
The program indicates that the file is encrypted or corrupted. The encrypted CUI files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the CUI file to another location.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file CUI to close. However, some background programs may block the CUI file while scanning. If nothing helps, please reset the device.
