Point code details are lost when importing a pt3 file from 3D Office. Can be kept if the points are imported from a TP3 file, but not always want to import the remainder of the project, or export the points and then reimport them to 3D Office before converting to a TP3 for export. Older versions of Magnet worked great. Issue found on V6.1 and 7. Older versions worked OK. Using V11.1 for 3D Office.
As a simple workaround, when Importing TP3, its possible to only import the Points and not the other objects if they are not needed by making sure they are unchecked during Import.
