A plot boundary is a closed polygon. The points where line segments join are called nodes. There are two segment types: line and curve.
Each plot has an area label, which refers to the plot as a whole. You can click the area label to select the plot. A plot can also have segment labels, and associated tables, which display information about the plot. Labels can contain user-defined property fields.
Each plot maintains information about its segments and nodes, and the area they enclose. Editing plot segments dynamically updates the plot properties. Deleting a segment can result in one plot merging with another.
