Paths are created as a set of points. To start building a path, left-click on the ground or floor in the desired location. Continue placing path points in this manner until the entire path is outlined. A path is completed by placing a new point over an existing point.
Paths must have a minimum of three points. Paths cannot self-intersect, which is when one side of a path crosses over a different side of the path.
By default, sides of a path are drawn at cardinal directions (90 degree increments). To draw the path side in free form, hold the Shift key while placing the path points.
Pressing Esc will cancel the current path. Pressing Delete will delete the previous path point.
