What is GatheringPlace?
GatheringPlace creates a triangular or trapezoidal assembly area symbol used in military and tactical mapping. It represents a designated gathering, staging, or assembly zone. The shape is defined by 2-3 control points that form a distinctive triangular gathering area with a flat base and converging sides.
How to draw
To draw a GatheringPlace, select GatheringPlace mode. Click 2-3 points on the map. The shape converges from a wide base to a narrow point or forms a triangular area. Double-click to finish.
