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 Auto RC's 4.5. Structural Navigator also leads on in-app purchases (none vs 8) and iOS requirement (9.1 vs 16.0). Auto RC's advantage is update cadence (every 3 weeks vs every 5 months) and review sentiment (75% vs 50%). On price, ads 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 4.5. That said, the two scores are not equally well evidenced: Auto RC has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Structural Navigator's written reviews are positive against 75% of Auto RC's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Structural Navigator ships an update every 5 months, Auto RC every 3 weeks. The most recent releases landed on October 5, 2026 and October 1, 2026 respectively.
