We recently scanned a large site with the NavVis VLX (29 datasets) with a total size of about 84 GB. The site covers roughly 93,000 m².

We processed everything locally instead of using the online platform. After cleaning and organizing the point cloud in Cyclone 3DR, the data was reduced to about 70 GB (E57).

I tried Autodesk ReCap for zone management, but it wasn’t very efficient at this scale. After testing a few different tools, I found Qbitech (qbitec.com) works best for bringing large point clouds into Revit. It’s fast, handles heavy data smoothly, and has great visualization tools, the X-ray view and other display modes are especially useful.

I’d like to share our workflow for generating a site model in InfraWorks using point cloud data. Our process began with acquiring a point cloud from the site. After cleaning and refining the data, we extracted high-detail contour lines from the areas of interest using Leica Cyclone 3DR. These contour lines were then exported in CAD format and used to create the site geometry within InfraWorks.

Additionally, we integrated the point cloud into InfraWorks for other purposes. However, for greater accuracy and reliability in site modeling, we recommend using CAD-derived contour lines rather than generating them directly in InfraWorks. This approach ensures a more precise and controlled representation of the site conditions.

What you should know about exporting in the Datasmith format is that the plugin exports the currently active view in Revit. This means that if you have a high-detail view active, the export will include high-detail elements, whereas a low-detail view will result in a lower level of detail in the export.

Secondly, the best workflow is to export each Revit file separately and integrate them into different software. This approach gives you better control and allows you to manage each file individually.
