Currently, web browsers have a maximum size limit of 2GB per tab for loading content. Procore's web viewer uses a proprietary 3D file format, and if the file is larger than 2GB, the browser may not be able to load the model.
If a model file is too large to view on a web browser, you'll see an error message when you try to view the model in Procore.
If a model file is too large to view on a web browser, you can try to view the model on Procore's mobile applications. See View Models (iOS) or View Models (Android). You can also reduce the file size and republish the model to Procore.
Below are recommendations for best practices in Navisworks® that can help to reduce the file size of models.

Organizing a 3D model into smaller, more manageable pieces can improve performance and optimise the model.
Removing duplicate geometry is an effective way to reduce file size in Navisworks. Duplicate geometry happens when the same object or part is added multiple times to the model. This can occur accidentally when linking different models together or when multiple team members author the same scopes of work.
Viewpoints with 'Save Hide/Required Attributes' or 'Override Appearance' settings turned on can increase the size of both the NWF and NWD files. This is because each viewpoint stores additional metadata for the state of every object.
While this issue might be unnoticeable on small projects, these settings can become problematic on large complex projects and files. The viewpoints alone can more than double the actual size of the file geometry and data. Removing or modifying viewpoints to remove these settings can reduce your file size.
Another viewpoint setting that can increase the file size is when clash reports are exported as viewpoints with the 'Preserve result highlighting' setting turned on.
Depending on the use case of the model, reducing the level of detail or high polygon count objects in a 3D model can reduce the size and improve performance of the model.
Point cloud data is often used to create detailed 3D models of existing structures, but it can also be very large and complex. To optimise a 3D model, you can remove unnecessary point cloud data from the model.
