Extract text from Surface mesh files (SUR)
To convert SUR Mesh files to another format, you need MountainsMap or other 3D software.
To convert other file formats to the "Surface Data File" file type, you need software like MountainsMap or a similar tool.
A .SUR file is primarily a Surface Topography Data file created by 3D surface profilers and microscopes. It stores precise measurement data and is heavily utilized by metrology software like MountainsMap. Alternatively, .SUR acts as a 3D collision mesh file in classic games like Microsoft Freelancer or a surface mesh in scientific visualization tools like Amira.
The major disadvantage of the .SUR format is its severe fragmentation. Because the extension is shared by completely unrelated industries (metrology, flaw detection, and video game modding), operating systems cannot natively open it. Scientific .SUR files are locked behind expensive, proprietary software licenses. Modding-based .SUR files require niche, often outdated community tools. Sending a .SUR file to a colleague guarantees they will not be able to open it unless they own the exact same software suite.
To make this data usable, conversion is mandatory. For surface analysis and point-cloud extraction, convert to CSV or XYZ to process the data in standard spreadsheet or scripting environments. For 3D visualization and printing, convert the mesh to STL or OBJ.
Convert.Guru analyzes your SUR file, detects the exact format, and lets you read the text inside.
Users also converted MNT, CMB and MPH files.
If you want to convert SUR file to , you can use MountainsMap or similar software from the "Surface Topography Data" category. In the File menu, look for Save As… or Export….
To convert files to SUR, try MountainsMap or another comparable tool in the "Surface Topography Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SUR converter.
