.3me — 3D Metafile Exchange
Hewlett-Packard · 1992
.3me files are a vector-based format for storing and exchanging 3D geometric data, primarily used in older CAD and graphics applications.
Key Features
- Vector-based 3D graphics storage
- Supports geometric primitives and attributes
- Binary format for efficient data handling
- Designed for exchange between 3D applications
Best For
- Compatibility with older Hewlett-Packard graphics software
- Precise storage of geometric definitions
- Lightweight representation of simple 3D objects
- Archival of 3D data from specific historical projects
Less Ideal For
- Modern 3D game development
- Complex scene rendering with advanced materials
- Animation and character rigging
- Interchange with widely used modern 3D software like Blender or Maya
- Web-based 3D experiences
Common Use Cases
- Storing 3D models for early CAD software
- Exchanging 3D geometric data between compatible programs
- Archiving 3D designs from legacy systems
- Technical drawing and visualization in specific engineering fields
How to Open It
- Try opening with specialized CAD or 3D modeling software that supports legacy formats.
- Look for converters that might be able to translate .3me to more common formats like .OBJ or .STL.
- If you have the original HP software that generated the file, it will likely open it directly.
What is a .3me file?
The .3me file extension stands for 3D Metafile Exchange. It is a vector-based 3D graphics format developed by Hewlett-Packard. This format is designed to store and exchange 3D geometric data, allowing for precise representation of objects and scenes. It supports various graphical primitives and attributes crucial for 3D modeling and rendering. While not as widely adopted as some modern 3D formats, it played a role in early 3D graphics applications and CAD systems.

Frequently Asked Questions
No, .3me is considered a legacy format and is not widely used in modern 3D graphics workflows.
It contains 3D geometric data, defined by a series of drawing commands and attributes, rather than a mesh or point cloud.
Technical Details
This format stores 3D information using a metafile approach, essentially a series of commands that describe 3D objects. It is a binary format, making it efficient for storage and retrieval. The structure allows for the representation of surfaces, curves, and other geometric entities.
