SPAblnd Global Function api_smooth_edges_to_curve

Generates a calibration curve fit to a list of edges.

Role: This API makes a single curve that approximates the given list of smoothly-connected edges. The list need not be sorted upon input. The curve and pointers to the edges corresponding to the start and end of the curve are returned. The curve is returned as a new CURVE with a use count of 1, and must be disposed of properly. first_edge and last_edge are pointers directly into the body. This API is used in blending, for example to find a defining curve for a variable-radius blend sequence, which parameterizes the blend surface and calibrates the radius function. Typical usage would be:

 CURVE *calibration_curve;
 EDGE *first_edge;
 EDGE *last_edge;
 api_smooth_edges_to_curve(ents, calibration_curve, first_edge, last_edge); 

 result = api_set_var_blends(ents, start_radius, end_radius, start_setback, end_setback,
                             calibration_curve, first_edge, last_edge, 0, 0, TRUE, TRUE, start_stop_ang, end_stop_ang); 

 calibration_CURVE->remove();
