The Mesh license must be enabled to use or view this option.
To empty a mesh:
In the Edit window, position your cursor on or just below the Mesh you want to empty. If you have two consecutive meshes defined in the Edit window, you must be on the mesh you want to empty.
Click the Empty a Mesh button from the Mesh toolbar, or select Operation | Mesh | Empty from the menu.
The Mesh is emptied of all its data.
Once this command has been applied to a Mesh, there is no way to restore Mesh data that was removed. Undo does not restore this data.
