Libraries are the heart of BIM. The extension (Library Container File) is a compressed archive that holds objects, zones, materials, and complex profiles.
The ArchiCAD file extension system is the backbone of Graphisoft’s flagship BIM software. Understanding these extensions is vital for managing architectural projects, collaborating with consultants, and ensuring long-term data security. Unlike basic CAD programs that rely on a single format, ArchiCAD uses a variety of specific extensions to handle everything from live design work to object libraries and archival backups.
| Extension | Full Name | Primary Use | | :--- | :--- | :--- | | | Project File | Standard working file (Single user) | | .pla | Project Archive | Self-contained backup / sending to others | | .bpn | Backup File | Auto-saved recovery file | | .bim | Teamwork File | Server-based multi-user file | | .lcf | Library Container | Compressed library folder | | .ifc | Industry Foundation Classes | OpenBIM exchange with Revit/Tekla | | .bimx | BIMx File | Client presentation / 3D walkthrough | | .tpl | Template File | Office standards & new project starts | | .gsm | GDL Object | Individual object (Door, Window, Furniture) | archicad file extension
For teams working simultaneously on a single building, ArchiCAD utilizes the .TPL and .BPN formats for management. A .TPL file is a Project Template. Templates are essential for firms to maintain standards, as they pre-define layers, pens, favorite tools, and structural settings. On the other hand, the .BPN file is an automatic Backup Project. ArchiCAD generates this file every time you save your .PLN. If a main file becomes corrupted or a mistake is made, changing the .BPN extension to .PLN allows you to recover the last saved version of your work.
Name the file; it will be saved as a file in your Embedded Library. Libraries are the heart of BIM
This review covers the primary file extensions used in Graphisoft Archicad, a leading Building Information Modeling (BIM) software for architects and designers. Understanding these formats is crucial for workflow efficiency, data integrity, and collaboration Top 4 Archicad File Extensions (Archicad Project File):
: A built-in node-based tool for creating parametric objects visually, similar to Grasshopper. Common Archicad File Extensions compressed version of an Archicad project.
A packaged, compressed version of an Archicad project. The .pla format consolidates the .pln file along with its embedded libraries and other dependencies into one portable file. It is commonly used for:
The extension (Template Project File) is the blueprint for how your office works.
