What is an AC file?

Automatic configuration script produced by GNU Autoconf; automatically configures software source code packages to adapt to several types of Posix-like systems; created by testing a software package for each feature the program might need in order to run a specific system; Autoconf then builds a list of system features that the package requires.

More Information

Autoconf scripts are typically named "configure.ac." The automatic configuration script is created by running the preprocessor program m4 with the configure.ac file as input.

.AC File Association 2

An AC file contains information about the appearance of a a 3D model in AC3D format. It stores various appearance information, such as meshes, texture paths, UV-mappings, and material definitions. AC files are typically created by AC3D, an application used to create 3D models for games, flight simulation, and virtual reality.

More Information

While AC3D is a popular program foo creating AC files, the files are most commonly used by the X-Plane and FlightGear simulators. AC files can even be used to create X-Plane .OBJ files in AC3D and using the X-Plane plugin to export to the X-Plane OBJ format.

Since AC files are saved in plain text, you can open and modify them using a text editor. To open an AC file with a text editor, you may need to change the .ac file extension to .txt. After viewing or saving changes to the file, change the file extension back to .ac.

NOTE: AC files used by FlightGear are often accompanied by an .XML file, which contains information that animates the object or scenery in the game.
