Troubleshoot model processing issues

A model may not successfully process for the reasons described below.

The model file is not a supported file format

If an unsupported file format is uploaded, the model won’t successfully process and there will be an error. The file extension must also be correct. See Models supported filetypes.

You can find a model's type by hovering over its icon in the model list.

An issue with the model file or processor

There are three reasons for file or processing issues:

1. The supplied IFC or Revit file has an export error which causes the model to fail to meet the IFC or Revit schema standard.  
   Note: If the IFC or Revit file export doesn’t match the schema standard leading to process errors, it’s worth discussing the issue with the vendor of the export tool as you may not be getting all the information in your model that you expect.
2. A file related issue occurred when processing the file.  
3. A system processing error occurred.

If you believe the file is a supported version and there are no errors in it, contact us so we can investigate the issue.

Model exceeded our limit

Model files in Revit or Navisworks format that are larger than 2 GB may not process successfully. If the limit has been exceeded, an error message will appear. To reduce the size of a model, we suggest dividing it up by discipline. There is no size limitation for IFC files.
