Convert STL to OFF

Smart Insights

Did You Know?

The STL format (Standard Triangle Language or STereoLithography) was developed by 3D Systems in the late 1980s and is one of the most common file formats for 3D printing.

STL files describe only the surface geometry of a 3D object without any representation of color, texture, or other attributes common to other 3D file formats.

OFF (Object File Format) is a simple geometry file format that specifies the geometry of objects through vertices and faces, commonly used in computational geometry and 3D model exchange.

This conversion is especially useful when you need to prepare 3D models for computational geometry algorithms, analysis, or compatibility with academic and research software that prefer the OFF format.

STL vs OFF Comparison

STL Format

  • Supports both ASCII and binary formats
  • Simple representation of geometry only
  • Industry standard for 3D printing
  • Widely supported by CAD software
  • Lacks material or color information

OFF Format

  • Plain text human-readable format
  • Efficient vertex-face representation
  • Popular in computational geometry
  • Support for simple color information (COFF)
  • Compact and easy to parse structure

Technical Insight

Converting STL to OFF involves transforming the triangle mesh data from the STL format into the vertex-face representation of the OFF format.

The process identifies unique vertices from the STL triangles, eliminating duplicates to create an efficient representation in OFF format.

Our converter ensures that the model's geometry is accurately preserved in the OFF format, ready for use in computational geometry applications, research, and analysis.

Converting to OFF is particularly valuable for researchers and developers working with geometric algorithms, mesh processing tools, and computational geometry libraries like CGAL.

Frequently Asked Questions

Why should I use an online STL to OFF converter?

An online STL to OFF converter allows you to quickly transform 3D models between formats without installing specialized software. It's convenient for converting models from any device with a browser.

Will I lose geometry or materials when converting STL to OFF?

Our converter maintains the original geometry. The OFF format is a simple, clear text format that represents 3D geometry, preserving the mesh structure from your STL file.

How long does the conversion process take?

Conversion time depends on the model size and complexity. Most conversions complete within a few minutes.

Is my model data secure when using this converter?

Yes, we prioritize your privacy. Your files are securely stored on our servers and automatically deleted after 24 hours to ensure complete privacy and security.

Is this tool free to use?

Yes, our STL to OFF converter is completely free to use without any hidden charges. You just need to create an account to get started.

How long do you store our data?

Your model data is temporarily stored on our secure servers and automatically deleted after 24 hours for your convenience and privacy.

What is the limit of STL file size?

The maximum STL file size limit for conversion is 100MB.
