Extract text from CAD plans (PLZ)
To convert PLZ plans to another format, you need Nemetschek Allplan or other Compressed software.
To convert other file formats to the "Proprietary Archive / CAD Project" file type, you need software like Nemetschek Allplan or a similar tool.
A .PLZ file acts as a proprietary data container, most commonly serving as a Dynapp application data package, an Allplan CAD project plan, or a Proteus SCADA RTU library. These files are typically created and opened with specialized software like Nemetschek Allplan for 3D architectural CAD projects, or Serck Controls Proteus for industrial systems. Many of these files utilize standard ZIP compression under the hood to bundle multiple project assets into a single file.
These are highly specialized, proprietary formats. Users often encounter them when receiving architectural models or automated system backups. Without the exact source software, which usually requires expensive licensing, the files are completely inaccessible. They are not supported by standard web browsers, generic 3D viewers, or typical document editors.
The best conversion targets depend on the file's origin. If it is a compressed data package, converting or renaming it to ZIP allows you to extract the raw assets. For Allplan CAD files, converting the project to standard architectural formats like DWG, DXF, or IFC is necessary for cross-platform collaboration, though this usually results in the loss of parametric BIM data.
This file format is difficult to open or convert because it relies on closed-source, proprietary structures. Often only the original software can properly read or export the data. However, you can drag and drop your file onto convert.guru to identify the format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format like standard ZIP compression, viewing or extraction may still be possible.
Convert.Guru analyzes your PLZ file, detects the exact format, and lets you read the text inside.
Users also converted JPG, STZ, OMS and DB0 files.
If you want to convert PLZ file to , you can use Nemetschek Allplan or similar software from the "Compressed Application Data Package" category. In the File menu, look for Save As… or Export….
To convert files to PLZ, try Nemetschek Allplan or another comparable tool in the "Compressed Application Data Package" 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 PLZ converter.
