Convert ER diagram or terrain files (TER) online for free
The converter easily converts your TER diagrams or terrains to various formats - free and online. No Microsoft Visio or or other Data software needed.
To convert other file formats to the "Diagram & Terrain Data" file type, you need software like Microsoft Visio or a similar tool.
A .TER file is a multi-purpose format that heavily relies on its context. Most commonly, it stores an Entity-Relationship Diagram (ERD) using an XML structure for database planning in tools like Active Query Builder and Microsoft Visio. In the 3D rendering sector, it functions as a Terragen Terrain File created by Planetside Software Terragen, holding detailed elevation heightmaps for generating realistic landscapes. Less commonly, it acts as a ZIP compressed appointment calendar for ASCOMP Terminplaner.
Sharing and managing .TER files presents significant real-world friction. Visio diagram files are strictly tied to niche enterprise tools, often requiring recipients to hold expensive Microsoft 365 subscriptions just to view a database layout. On the 3D side, Terragen files contain highly specialized elevation mesh data that is entirely unreadable by web browsers or standard image viewers, trapping your terrain data inside a single rendering engine.
To make these files usable, they require format shifting. For ER diagrams, convert .TER to PDF for reliable archiving or SVG for lossless web display. For 3D terrain, converting to OBJ or STL allows the elevation geometry to be imported into standard 3D modelers like Blender. Drop your file here on convert.guru to instantly analyze and convert it securely right in your browser.

Users also converted EXR, VDC, VMR and VSSX files.
If you want to convert TER file to DAE, MAX, BLEND, MA, MB, C4D or WRL, you can use Microsoft Visio or similar software from the "Diagram or Terrain Data Storage" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to TER, try Microsoft Visio or another comparable tool in the "Diagram or Terrain Data Storage" 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 TER converter.
