From the Command Line, type 'NodeRenumbering' or 'NR'

Reference Coordinate System

Set the direction of priority upon which the renumbering process will be based.

1st

Select the first priority reference, +X, -X, +Z or -Z.

2nd

Select the second priority reference. Depending on the first reference, (+X or -X) or (+Z or -Z) can be selected.

Order

Ascending

Renumbering will take place by increasing numbers.

Descending

Renumbering will take place by decreasing numbers.

Node

Note:

The following diagrams illustrate the renumbering process. The left diagram shows the default numbering for nodes assigned counterclockwise during mesh generation. The right diagram illustrates renumbering the default node numbers in the ascending order in the +X direction (first priority) and +Z direction (second priority), starting from 1.

Ascending

It is common to use 1 as the start number when renumbering node / element numbers for the total mesh.  When renumbering node / element numbers by selecting specific elements, the start number must be the one that has not been assigned to any element of the unselected elements.

X -> No,  O-> Yes
