Validate the quality of your as-is 3D model

NavVis IVION makes validating the geometric quality of as-is BIM models easy. Visually compare IFC models, point clouds, and 360° imagery within one solution. With support for predefined coordinate systems, the software ensures georeferenced model alignment, simplifies verification, and eliminates the need for third-party tools. Quickly check compliance and project requirements, including LOD and accuracy standards, and annotate issues in the software.

Highlight, share, and resolve deviations between point cloud and 3D model

Use geo-tagged points of interest (POIs) in NavVis IVION to mark discrepancies between your point cloud and 3D model. Add annotations, images, or links, and instantly share deep links to specific locations or measurements. This enables clear, visual communication with your team and stakeholders – streamlining validation, reducing rework, and eliminating the need for external tools or site visits.

Identify, measure and communicate discrepancies with Mark & Measure

Combine 360° panoramas, laser scans, and BIM models to help engineers interact with digital sites as if on site. Identify, mark, and measure deviations between the point cloud and 3D models for precise validation, capturing coordinate data and taking orthogonal measurements. Share findings with your BIM/VDC team or export them in standard file formats, such as .csv or .dxf, for use in third-party solutions, accelerating design validation, clash detection, and collaboration.

Optimize data handling with focused point cloud sections

Isolate and download selected point cloud sections in various file formats (.e57, .las, .rcs, and more) for use in third-party modeling solutions. Use the 3D crop box with orthographic projection to choose the data you need and spot deviations when validating your 3D model. Reduce data clutter, speed up your modeling process, and enable more precise analysis and cleanup.

Frequently asked questions

This brief FAQ covers common questions for both new and existing users. For more detailed information, existing customers can explore our Knowledge Base, or new visitors can contact our team directly.

How do I compare scan data to BIM models?

After uploading and aligning a BIM model, compare it to the scan data. Adjust its visibility and appearance using the View Settings or Site Structure panels. Customize colors and visibility for the entire model or specific components to improve clarity. In Mark & Measure mode, use the 3D crop box to create precise slices and easily spot deviations between the model and the point cloud.

What file formats can I upload to NavVis IVION to compare with point clouds?

NavVis IVION supports IFC files based on the buildingSMART International (bSI) data exchange standards: IFC2X3, IFC4x1, IFC4x2, IFX4x3 RC3.

How do I keep track of deviations when validating 3D models?

Use POIs or measurement annotations within NavVis IVION to indicate deviation points. If synced with an integrated Construction Management Platform, e.g. Autodesk Construction Cloud (ACC), POIs become issues and remain synchronized over time.
