💡 OFF to X: How to Convert Object File Format to DirectX 3D Model

How to Convert OFF to X?

Get started with OFF to X conversion today. Our clear, step-by-step guide and powerful tool make the process fast and error-free:

  1. 📥 Download and Install

    Download and install Autoconverter on your system. This application will let you to convert your OFF mesh files to X format - no additional CAD software required.

  2. 📂 Open Your OFF Mesh File

    Go to File > Open… to load your OFF mesh file (*.off), or drag and drop it directly into the application window. The model loads into the 3D viewport for inspection before converting.

  3. 💾 Save As X Format

    Go to File > Save As…, select X (*.x) as the output format, choose your destination folder and filename, then click Save to complete the OFF to X conversion.

OFF OFF File Format - 3D Object File for Polygon Meshes

The OFF (Object File Format) is a simple, ASCII-based 3D file format used for representing polygonal geometry in a lightweight, non-proprietary structure. Designed for academic and development use, the OFF format efficiently stores 3D model data using only vertices, faces, and optional edge information - ideal for geometry-focused workflows without material or texture metadata.

OFF File Features

  • Editable ASCII Structure: OFF files are plain text, easily viewable and editable in any standard text editor, making them perfect for manual modeling or debugging.
  • Supports Polygonal Geometry: Store 3D shapes using triangle meshes, quadrilaterals, or general polygons. Each face is defined by a list of vertex indices, allowing flexible model design.
  • Lightweight and Minimal: Unlike complex CAD formats, OFF excludes materials, textures, and metadata, focusing purely on geometric structure for fast, efficient modeling.

Convert OFF Files to Other 3D Formats

Our 3D conversion tools make working with OFF files fast and flexible. Autoconverter enables direct conversion of OFF mesh models to popular formats such as STL, OBJ, SKP (SketchUp), and PLY - preserving polygonal integrity throughout. For advanced workflows, Autoshaper can convert OFF files into NURBS-based formats like STEP, IGES, and BREP, ideal for CAD software and precision manufacturing.

X X File - Microsoft DirectX 3D Model Format

The .X file format is a legacy 3D graphics format developed by Microsoft for DirectX applications. Introduced in 1995, it was widely used in Windows-based 3D games and multimedia software to store mesh geometry, materials, textures, and animation data. Although now outdated, the X format remains important for archiving and converting legacy DirectX assets.

Key Features of the X File Format

  • Microsoft Origin: Created for use with DirectX on Windows 95 and beyond.
  • 3D Mesh Support: Contains vertex positions, faces, normals, and other mesh details.
  • Skeletal Animation: Supports bone-based rigging, keyframe animations, and skinning weights.
  • Texture Mapping: Includes UV coordinates for accurate image-based texturing.

Convert X Files to Modern 3D Formats

Preserve your legacy DirectX 3D content with our reliable Autoconverter and Automesher Application. Effortlessly convert .X files to STL, OBJ, SKP, STEP, 3DM, and other standard formats used in 3D printing, CAD design, and visualization software. Whether you are updating old game assets or integrating classic models into modern workflows, our X file converter ensures full compatibility and data fidelity.
