Extract text from CAD floor plans (PB1)
To convert PB1 floor plans to another format, you need Punch! Home Design Studio or other Cad software.
To convert other file formats to the "Proprietary Architectural Project File" file type, you need software like Punch! Home Design Studio or a similar tool.
The .pb1 file extension is primarily utilized by Punch! Home Design Studio as a floor plan and 3D architectural project file. It stores room layouts, material textures, object placements, and structural metadata. Additionally, the .pb1 extension is used as a CAD reinforcement schedule file in Nemetschek Allplan, a tube bending project file in Advanced Tubular ProBend, and a drawing file in legacy Power-CAD Pro.
The main disadvantage of the .pb1 format is its proprietary, closed nature. These files lock your architectural data into a specific vendor ecosystem. They lack native support in web browsers, operating systems, or even mainstream industry software like AutoCAD. If you do not have an active, expensive license for the original software installed on your machine, opening a .pb1 file is practically impossible.
To share designs with clients or construction teams, you need to convert .pb1 files into universal formats. The best targets are PDF for document viewing and printing, or DXF and DWG for interoperability with other CAD systems. However, extracting this geometry usually requires exporting directly from the native application.
Standard online converters routinely fail to process .pb1 files because they lack the proprietary parsing engines required to reconstruct the 3D meshes and schedules. Just drag and drop your file onto convert.guru to instantly identify the exact software version, inspect the file structure for extractable text, and convert it when a supported underlying format or embedded preview image is detected.
Convert.Guru analyzes your PB1 file, detects the exact format, and lets you read the text inside.
Users also converted PL1, PL2, PB, XD, LMK, CWZ and PB2 files.
If you want to convert PB1 file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Punch! Home Design Studio or similar software from the "Home Design & CAD Data" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to PB1, try Punch! Home Design Studio or another comparable tool in the "Home Design & CAD 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 PB1 converter.
