7. (Optional) Reorder the items in the Selected Sort Criteria For example, select the Z Coordinate and click Move Up twice so the order from top to bottom is: Z Coordinate, X Coordinate, Y Coordinate. This instructs the program to renumber beams parallel to the Y axis until no more beams are in that line. It then skips to the next selected entity along the X axis and renumbers those, again along the Y axis. Once it has reached the end of selected beams parallel to the X axis, it then skips to the next selected entity parallel to the Z axis and repeats the previous procedures.
8. Click Accept. A message dialog opens with the status of the renumbering operation.
9. Click OK to dismiss the message dialog. The selected beams are renumbered following the indicated pattern.
