Editing the block polygons

You can also interactively edit the polygons you have digitised or imported using existing String Design tools (Copy, Move, Insert Mode, Delete) and block-specific tools (Merge Blocks, Split Blocks).

Note that you can copy selected blocks in the same way you can copy selected rows. When you drag selected blocks, the blocks are moved. If you hold down the CTRL key when you begin dragging, a copy of the blocks is created. Any holes in the block are also copied.
