5. Create Block Boundary Polygons

Strip solids are cut into blocks and benches using polygon block boundaries. The Measure tool is used against a reference layer to determine the distance and bearing required when drawing an initial boundary line:

The Measure tool can also be used to determine the block size before boundary lines are created using the Offset tool (with the Multiple Offsets option selected).

To close-off the lines to create polygon block boundaries, the Create Shape tool is used with the Snapping mode set to Snap to Segment:

Once the block boundaries have been drawn, the next step is to convert the lines into closed polygons using the Create All Closed Areas tool:

The block polygons are then sequentially numbered with a Block number attribute from North to South using the Set Attributes by Direction tool.
