BIMcollab vs F3D

BIMcollab brings together document management, BIM coordination and model checking for collaboration on buildings and infrastructure. Its WebViewer supports IFC models, while BIMcollab Zoom is a downloadable viewer for Windows and Mac OS X. Zoom includes Smart Views, clash detection and IDS checks; its free mode supports viewing, annotations, BCF issue management and visual validation with Smart Views. Issues can be managed using BIM-tool plug-ins and exported as BCF, PDF, CSV or XLS. BIMcollab lists more than 35 integrations, including Power BI, Solibri, Trimble Connect, AutoCAD, Autodesk Docs and Revit. All plans list unlimited projects; Basic includes 10 GB storage per space, while Advanced and Enterprise list unlimited storage. A free plan and free trial are available. Paid pricing ranges from €12.50 a month for Basic with annual commitment to €39 a month for Enterprise billed monthly. Cloud data is stored in the Netherlands unless the customer uses an on-premise installation. BIMcollab is headquartered in Eindhoven, Netherlands, and was founded in 2014.

F3D is free software for viewing 3D data, browsing models, and generating renderings. It supports lighting and materials for realistic rendering, animations with GPU-accelerated skinning for character rigs, and visualization tasks such as CAD, Gaussian splatting, volume rendering, and scientific work. Its supported formats include VTK, STL, DICOM, STEP, OBJ, glTF, FBX, USD, IFC, and Gaussian splat files, among many others. Packages are available for Windows, macOS, Linux, and Android, and a browser viewer can open or accept dropped files and provides rendering and display controls. Developers can use a Python package, a beta JavaScript/WebAssembly package, or the libf3d C++ library with Python and Java bindings. F3D is distributed under the BSD 3-Clause License. Some capabilities have specific limits: FBX PBR materials and Alembic materials are unsupported, while Gaussian splatting requires OpenGL 4.3, which macOS does not support. Documentation also says volume rendering and HDRI need a decent GPU. Plugins can vary by package.
