Please make sure they are correctly sorted.{p_end} {p2coldent : {opt smooth(num)}}A smoothing fit variable between 0 and 1. A smaller value will result in larger and rounder fits. A high value will have tighter bends but if the points are bunched together, then this might also create undesireable loops. Default is {opt smooth(0.5)}.{p_end} {p2coldent : {opt close}}Close the loop between the first and the last point.{p_end} {p2coldent : {opt points(num)}}Number of points to evaluate the curve between two points. Higher points will result in more accuracy but will be slower. Default is {points(100)}.
