The "Fill closed polyline with symbol" option on the gCADPlus drop menu can be used in a number of ways.
A useful gCADPlus tool fills any space delineated by a closed polyline with a symbol. In this movie, we create a custom symbol to indicate ground cover planting and in one action, fill the space with multiple copies of the design at an indicated spacing interval.
Tip: The symbols when placed will of course be located inside the polyline. If you want the symbols to cover the boundary (say to spill over a path), draw thE polyline a little larger than the desired fill area. When complete, simply remove the polyline. The figure below shows the tool in action. The red polyline defines the area to be filled.
