What is an .AC File?

The .ac format stores 3D geometry mesh data, scene node hierarchies, material definitions, and camera viewports used in 3D modeling, game development, and CAD engineering.

Associated Software & Origin

Created by 3D authoring applications such as Blender, Autodesk 3ds Max/Maya, Apple SceneKit, Godot, SketchUp, and AutoCAD.

Data Structure & Characteristics

3D scene files can store binary geometry buffers, vertex normals, polygon indices, texture reference paths, and animation tracks.

What ZumiFiles Can Inspect

ZumiFiles renders an interactive 3D WebGL viewport canvas with OrbitControls, allowing you to rotate, zoom, and inspect object mesh stats without desktop 3D software.
