Products and versions covered

Issue:

Users reported that while opening a Revit file, the following error message is received:

Schema Conflict when Loading a File

The file being loaded is causing a conflict with the existing data in the model. What do you want to do?

The file contains data of schema Enigma/Traceit…"

Enigma	Traceit

Causes:

This issue can be caused by either of the following:

A file containing one of the schemas was accessed (through opening a project or family, or accessing a linked model). This loads the first schema into memory.
A file containing the other schema is accessed. This leads to the warning.

Solution:

Revit 2025 and later:

Added automatic cleaning of problematic Extensible Storage schemas during file upgrade to Revit 2025 per Release Notes.

Revit 2024 and prior:

Download/install the attached InviewLabs.CleanProject.Installer.msi.
Open your Revit project and run Purge Unused command.
Select Check None.
Find the schema under Other Styles -> Extensible Storage Schemas, and check it.
Click OK.
Save.
Close Revit.

Workshared models: If the model is work-shared, after going through the steps above, re-open and check if the schema shows up in Purge Unused, and if so purge it again.then save and sync again.
