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. Features: • Hyperlinked 2D & 3D views with interactive markers • Trace 2D drawings on 3D with animation • Access project and building component-related BIM information • Superfast 2D documentation viewer • Game-like 3D navigation • Gravity & Egress recognition • Option to access a Hyper-model element from outside of the app • Google Cardboard VR support on iPhones • Real-time 3D cutaway • Cut Plane Color Picker • Shading options • Shadow casting • Sun positioning by date and time • Measure in 3D and on 2D layouts • Explore 3D models of any size thanks to the streaming 3D engine • Save Favorites • Create compelling presentations • Print support, PDF export • Keyboard, mouse, and gamepad support BIMx Pro features, available with Graphisoft account-based licensing: • Issue creation – BCF-based documentation revisioning • Hide 3D elements and control Layer visibility in the virtual model • Customizable Cut Plane Explore the BIMx Pro features with the built-in demo model.

Structural Navigator is the ideal app for the mobile review of 3D structural models. Structural Navigator allows designers to view, query, and red line structural models in 3D from anywhere using a mobile device. With Structural Navigator users can: * Navigate through 3D models using zoom, rotate, pan, walkthrough, and flyover commands * Color code elements within the model according to specific properties (for example, slab thickness, pipe diameter, etc.) * Filter models based on members with common member attributes * Check for clashes between different types of objects * Add markups with status, due date, responsible party, and additional information * Interactively query members for all property values Structural Navigator reads Bentley's i-model format, to which any ISM repository can be easily converted with a single operation. The process is simple. Build a data-rich ISM repository using any Bentley ISM-compliant applications desired, convert the ISM repository to i-model, and then review in Structural Navigator. Structural Navigator can read models from any of the following sources once published to i-model: - STAAD - RAM - SACS - AECOsim - Revit - Tekla - ProStructures - Dlubal RFEM

Verdict

The call

The clearest difference is rating: Structural Navigator at 5.0 against BIMx's 4.0. Structural Navigator also leads on monetization model (free vs free with in-app purchases) and iOS requirement (9.1 vs 16.0). BIMx's advantage is ratings volume (167 vs 1) and update cadence (every 5 weeks vs every 5 months). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Structural Navigator holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: BIMx has 167 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of BIMx's written reviews are positive against 50% of Structural Navigator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

BIMx ships an update every 5 weeks, Structural Navigator every 5 months. The most recent releases landed on October 7, 2026 and October 5, 2026 respectively.
