This free lisp is useful while working with Land Survey Drawings. Note that in CAD if you have to delete a layer there should not be any entities in that layer. When you are creating entities in a layer programmatically (using lisp), then it may require that you erase all the entities in that layer and then run the program. Using this free lisp 'Delete Layer' you will be able to delete all the entities in the current drawing.
