Convert THL to another file type
To convert THL design files to another format, you need Total 3D Home Design or other 3D software.
Convert a file to THL
To convert other file formats to the "Home Design Project File" file type, you need software like Total 3D Home Design or a similar tool.
About THL files
The .thl file extension represents a Total 3D Home Design Project file. These files are used to store architectural floor plans, 3D room models, furniture layouts, and material textures. They are created and opened exclusively using Total 3D Home Design by Individual Software.
The primary disadvantage of the .thl format is its proprietary, closed nature. You cannot open these files in standard 3D modeling programs like Blender or AutoCAD. Sharing a .thl file with a contractor or architect is problematic because the recipient must purchase and install the exact legacy Windows software to view the design.
To make the data usable, users typically need to convert .thl files to generic CAD formats like DXF and OBJ for 3D editing, or PDF and JPG to share simple floor plans. During this conversion, specific lighting setups and proprietary textures are often lost.
Because this file format is a closed system, it is notoriously difficult to open or convert with standard web tools. Often, only the original software can properly read or export the 3D mesh data. If our analysis detects a supported underlying or embedded format, viewing or extraction may still be possible.
Convert.Guru analyzes your THL file, detects the exact format, and lets you read the text inside.
If you want to convert THL file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use Total 3D Home Design or similar software from the "3D Home Design Project" 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 THL, try Total 3D Home Design or another comparable tool in the "3D Home Design Project" category.
The THL 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 THL converter.
