AC File Extension

What is AC file?

Files with the AC extension belong to the category of 3D model files.

What do AC files contain?

Files with the AC extension contain three-dimensional models generated in the AC3D software. This software allows for creating 3D objects and modifying existing projects, and it is mainly used during video game production. AC3D has been in development since 1994. In AC files, stored are complete three-dimensional models, hence the contents of these files can be distinguished:

• sizes and locations of objects,
• dimensions of individual surfaces,
• properties of planes,
• textures and fillings,
• references to other system resources.

What are AC files used for?

Files with the AC extension are most often used to save work conducted in the AC3D application. In this way, three-dimensional model projects can be transferred between computers or shared on the net, for instance, via file exchange platforms.

AC files can also be converted into other formats using special programs called converters. This allows for opening AC files in applications that do not natively support the AC3D standard. Nonetheless, it is worth knowing that many programs for creating and animating three-dimensional graphics enable importing 3D models directly from AC files without the need for their prior conversion to other formats.

Programs which support AC file extension

The following listing features AC-compatible programs. AC files can be encountered on all system platforms, including mobile, yet there is no guarantee each will properly support such files.

How to open file with AC extension?

Being unable to open files with AC extension can be have various origins. What is important, all common issues related to files with AC extension can be resolved by the users themselves. The process is quick and doesn’t involve an IT expert. The list below will guide you through the process of addressing the encountered problem.

Step 1. Download and install Blender

Problems with opening and working with AC files are most probably having to do with no proper software compatible with AC files being present on your machine. The most obvious solution is to download and install Blender or one to the listed programs: AC3D, 3D Object Converter. Above you will find a complete listing of programs that support AC files, classified according to system platforms for which they are available. The safest method of downloading Blender installed is by going to developer’s website (Stichting Blender Foundation) and downloading the software using provided links.

Step 2. Update Blender to the latest version

You still cannot access AC files although Blender is installed on your system? Make sure that the software is up to date. Sometimes software developers introduce new formats in place of that already supports along with newer versions of their applications. If you have an older version of Blender installed, it may not support AC format. The latest version of Blender should support all file formats that where compatible with older versions of the software.

Step 3. Set the default application to open AC files to Blender

After installing Blender (the most recent version) make sure that it is set as the default application to open AC files. The method is quite simple and varies little across operating systems.

Selecting the first-choice application in Windows

• Clicking the AC with right mouse button will bring a menu from which you should select the Open with option
• Select Choose another app → More apps
• Finally select Look for another app on this PC, point to the folder where Blender is installed, check the Always use this app to open AC files box and conform your selection by clicking OK button

Selecting the first-choice application in Mac OS

• From the drop-down menu, accessed by clicking the file with AC extension, select Information
• Proceed to the Open with section. If its closed, click the title to access available options
• Select Blender and click Change for all...
• Finally, a This change will be applied to all files with AC extension message should pop-up. Click Continue button in order to confirm your choice.

Step 4. Check the AC for errors

Should the problem still occur after following steps 1-3, check if the AC file is valid. It is probable that the file is corrupted and thus cannot be accessed.

1. Verify that the AC in question is not infected with a computer virus

If the AC is indeed infected, it is possible that the malware is blocking it from opening. Immediately scan the file using an antivirus tool or scan the whole system to ensure the whole system is safe. If the scanner detected that the AC file is unsafe, proceed as instructed by the antivirus program to neutralize the threat.

2. Check whether the file is corrupted or damaged

If the AC file was sent to you by someone else, ask this person to resend the file to you. It is possible that the file has not been properly copied to a data storage and is incomplete and therefore cannot be opened. It could happen the the download process of file with AC extension was interrupted and the file data is defective. Download the file again from the same source.

3. Verify whether your account has administrative rights

Some files require elevated access rights to open them. Log out of your current account and log in to an account with sufficient access privileges. Then open the AC3D Geometry Format file.

4. Check whether your system can handle Blender

If the systems has insufficient resources to open AC files, try closing all currently running applications and try again.

5. Verify that your operating system and drivers are up to date

Latest versions of programs and drivers may help you solve problems with AC3D Geometry Format files and ensure security of your device and operating system. It is possible that one of the available system or driver updates may solve the problems with AC files affecting older versions of given software.
