This command enables the user to replace a floor with a new DXF file, using the same method as described for the menu item: Building > Add Floor. The wall and building lines are deleted for the old floor and the lines for the new floor plan are used to replace the old ones. All exit, link and person data is maintained.
This command is very useful if you which to make changes to one floor plan after a problem has come to light during the distance mapping, route testing or simulation stages.
You need to make the changes to the DXF file with a CAD package, and import it back into the current building, into the same floor, using this command.
