Graphisoft’s BIMx is an interactive app for exploring BIM projects and linked documentation sets created in Archicad, MEP Designer, and DDScad. Please download to visualize or collaborate on architectural design projects on your mobile device(s). BIMx offers professional building visualization with game-like navigation to explore and visualize architectural projects. BIMx features the ‘BIMx hyper-model’ – allowing non-design professionals to explore and fully understand architectural design intent, view project deliverables, and access element-level BIM data. BIMx links the 3D model with the relevant 2D documentation layouts, providing a seamless way to view the 3D cutaway model in the context of a 2D layout — and vice versa. BIMx connects the construction site with the architect’s office for streamlined collaboration. Real-time model cut-throughs, in-context measuring, and project markups in the model context make BIMx your best on-site BIM companion. Drive the design narrative on the building site for fast, specific client feedback.
