Convert IFC to POTM via Java

What is IFC file format?

An IFC (Industry Foundation Classes) file is a model file used in Building Information Modeling (BIM) programs. It is an open file format specifically designed for the architecture, engineering, and construction industries. IFC files store comprehensive information about a building or facility, including spatial elements, materials, and shapes.

The IFC format was initially developed by the Industry Alliance for Interoperability, which later became BuildingSMART. Its purpose was to establish a platform-neutral file format that enables seamless interoperability between different BIM software applications. Since its inception in 1996, the IFC format has undergone multiple revisions to enhance its capabilities and accommodate evolving industry requirements.

Opening an IFC file can be done using various BIM applications. Popular options include Autodesk AutoCAD Architecture (Windows), Tekla BIMsight (Windows), and GRAPHISOFT ArchiCAD (available on multiple platforms). Additionally, there are free IFC file viewers like Areddo that allow users to view the content of an IFC file without the need for specialized software.

Converting an IFC file to other formats is also possible using specific BIM applications. Autodesk AutoCAD Architecture and GRAPHISOFT ArchiCAD, for example, offer options to export IFC files to different file types. This enables the conversion of IFC files into formats such as DWG (AutoCAD Drawing), DXF (Drawing Exchange Format), DGN (MicroStation Design), C4D (Cinema 4D Model), 3DS (3D Studio Scene), SKP (SketchUp Document), DAE (Digital Asset Exchange File), OBJ (Wavefront 3D Object), U3D (Universal 3D File), and PDF (Portable Document Format).

The IFC file format has played a vital role in facilitating collaboration and interoperability among professionals in the architecture, engineering, and construction industries. It allows the exchange of rich and comprehensive data models, enabling effective communication and coordination throughout the lifecycle of a building or facility project.

What is POTM file format?

A POTM file refers to a macro-enabled presentation template created using Microsoft PowerPoint, a software program used for creating slide show presentations. It includes default images, slide templates, macros, and formatting. POTM files are commonly used by PowerPoint users to create multiple .PPTM files with consistent designs and macro settings.

POTM files offer additional functionality compared to typical presentation files, as they support macros. Macros are script-like functions that automate repetitive tasks within PowerPoint. Users can record macros that can be replayed to perform specific actions and assign them to buttons or keystrokes for convenient execution. To record a macro, users can select View → Macros in PowerPoint.

For general presentation creation, users can save their files as .PPTX or .POTX files. However, if they want to create a template that incorporates macros, they can save their presentation as a POTM file.

It’s worth noting that POTM files were introduced by Microsoft when they released Microsoft Office 2007.

To open a POTM file, Microsoft PowerPoint (2007 or later) is the recommended application for full support of presentation formatting and embedded macros on both Windows and macOS. Alternative applications like Apache OpenOffice Impress, Kingsoft Presentation, and Apple Keynote can also open POTM files, but some formatting and macros may not be fully preserved. For Mac users looking to view a POTM file without editing, Apple Preview (bundled with macOS) or Google Drive, a free cloud storage service, can be used.

Online platforms like Google Slides allow users to upload POTM files for viewing, editing, and conversion. However, it’s important to note that Google Slides does not support macros.

To convert a POTM file, various presentation applications including Microsoft PowerPoint, Apple Keynote, and OpenOffice Impress offer conversion capabilities. In Microsoft PowerPoint for Windows and Mac, users can select File → Save As and choose from formats such as .PPTX, .PPT, .PDF, .ODP, .XPS, .MP4, .WMV, .JPEG, and .PNG to convert the POTM file to their desired format.
