Wipe-Out Wipe-out – type ‘WI ‘as the shortcut tool then pick the option from the list. Wipe-out hides a selected area. It has a similar effect in essence to TRIM. But the bonus is its non-destructive enabling you to keep the data beneath and edit it later if needed. Choose Wipe-out Then draw the outline in which you wish to cut out. The computer recognises rectangles as polylines so if you have drawn a polyline or a rectangle you can choose this option rather than tracing it. Keep or discard the original.

Divide Tool ‘DI’ - Divide Tool Cuts objects up into segments and displays them as NODES. Make sure your NODES are under the OSNAP tool. The symbol for a node is a circle with a cross and then a tick box with node.
