Convert TEK to another file type
To convert TEK Geotechnical files to another format, you need LH Logismiki Tekton or other Cad software.
Convert a file to TEK
To convert other file formats to the "Structural and Geotechnical Data" file type, you need software like LH Logismiki Tekton or a similar tool.
About TEK files
The .TEK file format is a highly fragmented extension used by several unrelated technical industries. Most commonly, it functions as an XML-based structural analysis project file for LH Logismiki Tekton. It is also standard for geotechnical soil investigation data in the Finnish geotechnical framework (opened via tools like 3D-Win), and as rebar detailing data in Tekla Structures. In other edge cases, .TEK files store tidal water level data for Deltares Delft3D simulations, or floor mapping data for Ecovacs robotic vacuums.
The primary disadvantage of the .TEK extension is its severe lack of standardization. Because multiple niche, proprietary applications use the exact same file extension, users face constant format collision and compatibility failure. A structural CAD .TEK file cannot be read by geotechnical software, and vice versa. Furthermore, these files are generally locked behind expensive, specialized engineering suites, making them extremely frustrating to share with clients, contractors, or external stakeholders who do not possess an active software license.
To bypass these restrictions, converting your .TEK file is heavily recommended. For structural analysis and rebar data, convert to DXF or DWG to ensure broad CAD compatibility, or PDF for immutable archiving. For geotechnical soil logs and tidal water level data, convert the file to CSV or XLSX so the tabular data can be manipulated in standard spreadsheet applications.
Convert.Guru analyzes your TEK file, detects the exact format, and lets you read the text inside.

The TEK Converter Story
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 TEK converter.
