To be able to work (somewhat) with large coordinates, being able to strip and re-apply a global coordinate offset would be very helpful.
Example:
A site/model created in i.e. Revit, with a reference box placed that is the local 0,0,0 in which the global offset is applied to. We encounter this at work frequently.
ATM I manually remove the global offsets with ifcpatch by negating the global offset (localplacement/axis2placement3d)
python -m ifcpatch -i "Model with real coordinates.ifc" -r OffsetObjectPlacements -a -363799960.076 -6661200126.685 -28300.000 0
Then, I do work, and export a new IFC with the reference box in 0,0,0, and re-apply the global offset with the same ifcpatch script.
Proposal:
Make it possible to remove global offset on import
Make it possible to apply a global offset before export (either in export dlg, or in IFC manager settings)
Afaik this must be set on the IfcSite
For future GIS features, being able to do the same for imported, real-world-coordinated DWG/DXF or Shape files would be useful.
