When using Fence File, I was wondering..........does the newly created file retain the same global origin?
Yes, it does. As well as other DGN file settings.
We used to use the File Fence command to create a seed file for files that come from others. Place a fence around nothing, type FF= and press return. Use the dialog box to browse to a location and give the seed file a name. Last step, issue a datapoint to accept the empty fence contents, and you have a new seed file.
We also used to use an MDL to reset the GG number and TN number, but I do not think it is available anymore.
