The Block Layers function is used to control the block layer inclusion table to be used by the Block Move, Block Copy, and Block Delete Inside functions. Data that is on layers that are not selected will not be modified by subsequent block operations.
When you select this function, a dialog box will appear which will display the layer selections. You can click on a layer to add or remove it from the list of layers to be processed.
A containment block must be defined before this function can be used.
