Split
Choose this option to split any selected blocks along the split lines.
Set the Edit Bar options. You can either split blocks that are already selected or select blocks to split by pressing Select. This will run the Select Window tool. Once the block(s) to be split have been selected you should right mouse click to exit this mode. Then draw the split lines by picking the start point and the end point of each line. The split lines will be displayed as they are drawn. When you have added all the split lines required press Split and any selected blocks will be split along the drawn split lines. The new blocks will be renamed as the original block followed by _1, _2 and so on.
The blocks can be selected using any of the selection tools before the Split Selected tool is activated.
