Graphisoft BIMx vs Sketchfab

Graphisoft BIMx brings layouts, 3D models, and BIM data together in a .bimx file for architects, engineers, construction teams, and clients. It supports game-like navigation through 3D models and links from Hyper-models to project documentation. BIMx Issues lets users mark up 2D and 3D views, with BCF-compliant issues. Presenter and Gallery support presentations and client exploration, while the Web Viewer can be embedded on a website. Users can inspect building-element details such as fire ratings and manufacturer-specific properties. Graphisoft says facility managers and owners can connect Facilities Management databases with models for maintenance. Models can be shared by web link through BIMx Model Transfer; private Hyper-model sharing is for Graphisoft Subscribers, SSA, and Forward users. BIMx is free on the web, Windows, macOS, iOS, and Android. Opening projects in the mobile and desktop apps requires a registered Graphisoft ID; without signing in, users can access sample content and one additional custom model. After sign-in, authentication can last up to one year with occasional online access, or up to seven days offline.

Sketchfab is a platform for publishing and finding 3D content through an interactive viewer. The viewer can be embedded on websites, allowing 3D and VR viewing without leaving the host site. Its built-in editor adjusts orientation, materials, lighting, camera parameters, and post-processing filters. Upload formats include OBJ, FBX, Blender, STL, and glTF, and exporter plugins are available for Blender, Maya, SketchUp, Unity, and ZBrush. APIs support model uploads, data access, downloads, and viewer control or embedding. The Download API provides glTF, GLB, and USDZ, not source formats such as FBX and OBJ; owners control whether their models are downloadable. Basic is free and allows model files up to 50MB. Pro costs $15 a month billed yearly, with a 200MB model limit and private uploads. Premium costs $79 a month billed yearly, with a 500MB limit and advanced embed customization. Enterprise pricing is by quote.
