Dear,

I have a dental model (STL file) and a fiducial file (FCSV). In 4.10, all fiducials are on the model. However, in 4.11, the fiducials are in the air instead of on the model. It looks like the model has been transformed, but I didn’t apply any transform on it. Any suggestions?

See explanation why this happens and how to fix here: [https://www.slicer.org/wiki/Documentation/Nightly/Developers/Tutorials/MigrationGuide/Slicer#Slicer\_5.0:\_Models\_are\_saved\_in\_LPS\_coordinate\_system\_by\_default](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Tutorials/MigrationGuide/Slicer#Slicer_5.0:_Models_are_saved_in_LPS_coordinate_system_by_default)
