From the developer:
ActiveLine lets you create polylines whose dimensions (area and perimetric dimensions) are reactive. Thoses polylines react automatically to AutoCAD commands and update themselves as soon as the polyline is modified. So, moving a vertex of the polyline will cause the recalculation of the area and the modification of the dimensions attached to this vertex.
