Enter the Mesh module.
From the main menu bar, select .
Abaqus/CAE displays the Edit Mesh dialog box.
The Undo section of this dialog box includes the Undo and Redo buttons and next to each button descriptions of the mesh editing action that will be undone or redone when you click it.
Click Undo to undo the indicated mesh editing operation or click Redo to redo the indicated mesh editing operation.
Abaqus/CAE performs the indicated change.
Continue editing the mesh or undoing or redoing changes; close the Edit Mesh dialog box when you are done.
Note:
When you perform a new mesh editing operation, or any other operation that alters the mesh , any redo information about the affected part or part instance will be lost. Undo and redo information is also deleted if you delete a region mesh, apply top-down meshing, or add partitions if the added partitions require part of the mesh to be deleted.
