IFC Grid Wrong position

[Baonq]

I export IFC files from Revit 2022 (IFC 2x3 Coordination View 2.0) then append those files to Naviswork 2023. But Grids is wrong place. 

I try change Conversion Method in File Reader Option from v3 to v1 (Legacy) and refresh model, grids are show in model, but I can use this to determine the position of clash.

How can I fix this Error?

Thank all so much.

You mentioned exporting IFC models from Revit. Is the model geometry in Revit all native Revit objects or have you imported/linked other geometry from other file formats, DWG, IFX, etc.

Unless it is absolutely critical, don't export IFC files out of Revit to use in Navis. Use the Navisworks add-in to create a NWC file. While Navisworks can use IFC files, avoid it.

I Export all native Revit model to IFC. When i open this IFC file by Solibri Anywhere, it can detection grids and turn on/ off grids. I think Naviswork's IFC support is not good.
