This command processes a group of
points by screen selection or point number range, and then computes
the best fitting centerline by least squares. Each line segment in
the centerline is calculated by the best-fit line method and each
arc segment is calculated by the best-fit arc method. The line and
arc segments are then made to be tangential.
In the process options dialog, the Snap Tolerance is the max offset from the point to the line or arc segment in order to be counted as part of that segment. The Max Radius controls the maximum radius for arc segments that the program will fit to the data.The residual for each point is the perpendicular distance from the point to the best-fit centerline. The results are shown in a dialog and you can toggle each point for whether to include in the calculations. Points that are toggled off are not used for calculating the centerline but are still used in the residual report. The Remove function removes the point from both calculation and residual reporting.
