Dashes are built perpendicular to the brow of the slope, while the corners are smooth turns, avoiding overlaps and intersections of the strokes. Also in the process of building, there is a tool for allowing mass edit position strokes.

Compare the length of the slope and step hatch to the number of lines does not exceed 2000, or the calculation can take a long time.
