1. Overview
If you see the warning message "This BIM file may contain outliers that could affect data precision..." in the BIM Editor, it means your uploaded model contains residual objects located far outside the main building scope.
2. Why is this a problem?
These outlying objects significantly enlarge the model's bounding box. Processing a model with an excessively large bounding box can lead to the following issues:
Loss of geometric precision due to floating-point degradation.
Visual rendering artifacts, such as misaligned, flickering, or distorted elements.
Revision failures, where the system cannot accurately match elements between model versions.
3. Resolution: How to Clean Up Your BIM File
To ensure optimal performance and accuracy, you need to hide these outlier objects in your original authoring tool (e.g., Navisworks) before re-uploading.
[Cleanup Procedure in Navisworks]
Open your original file in Navisworks.
Select the valid building scope: Carefully select only the objects that belong to the actual building or project area.
Hide the outliers: Right-click and select Hide Unselected. This will hide all residual objects scattered outside your main model.
Save the file: Save your changes. (Hidden objects will be automatically excluded during our system's processing).
Re-upload the cleaned file:
For Direct Uploads: Go to your BIM file list and select "Replace" to upload the newly saved file.
For ACC (Autodesk Construction Cloud) Users: Re-upload the cleaned file to your ACC environment, then sync/update the model in our platform.
