Definition of length, height and area
The Length, Height and Area in the respective columns on the Triangulation Settings form are based on an object bounding box which extends to the extreme nodes of the polyline set as illustrated in the image below:
Schematic figure showing how 'length', 'height' and 'area' are defined. Extreme nodes of the polyline set are detected (dashed circles) which define the object bounding box. The diagonal of the box in top view defines 'length', the height of the box defines 'height'. The 'area' is 'length' times 'height' click to enlarge
