What is AC file?

The file in the AC format belongs to the Text Files category. It was designed by Inivis Limited. Additionally, the Text Files category contains 440 of other files. AC3D Geometry Format is supported by 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The main program that supports this format is Blender. This was created by Stichting Blender Foundation. Alternatively, you can use 2 other programs. AC3D, 3D Object Converter will apply when it is not possible to use Blender.

How to open AC file?

An often recurring problem with AC3D Geometry Format is that AC is not associated with the correct program file. This is manifested by the fact that AC files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the AC 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 Blender

The first step is to check if the computer has the Blender program installed. The easiest method is to use the system search engine by entering the program name Blender in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file AC with Blender. Below you will find a list of applications that support AC files.

Programs to open AC file

Remember to download programs supporting AC files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Blender with AC files

However, it may happen that the application itself does not cause the AC file to open in the Blender application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the AC file with the Blender program.

Step 3. Update Blender to the latest version

If, despite the association of the Blender program with the AC3D Geometry Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Stichting Blender Foundation page and install.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the AC file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our AC file. Sometimes virus-infected AC files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the AC file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular AC file corruption. The easiest way to restore the file is from a backup or by contacting Inivis Limited, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted AC files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
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. Copying the AC file to another location will fix the problem.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
