"""
This script is an alternative to _CrvDeviation and
RhinoCommon's Curve.GetDistancesBetweenCurves; it is used by other scripts.
Example of erroneous results from Curve.GetDistancesBetweenCurves:
https://discourse.mcneel.com/t/function-of-curve-getdistancesbetweencurves-tolerance-parameter/190553
Setting LwrLimit, UprLimit, or MaxDistToRegard to 0 will disable that option.
MaxDistToRegard is the lowest value, over which the distances will be ignored.
Send any questions, comments, or script development service needs to
@spb on the McNeel Forums, https://discourse.mcneel.com/
"""
"""
170927: Created.
...
171204: Now polycurves and polylines are "exploded" into segments. If they are not,
Curve.GetDistancesBetweenCurves sometimes fails or produces erroneous results.
Curves from curve set A are not selectable for set B even though they previously were removed anyway.
...
240903-10: Added optional 2 curve input routine. Removed some functions. Refactored.
Add display conduit similar to _CrvDeviation for when Mode=Abs.
Trialing a UX different than _CrvDeviation for when Mode=Abs,
that gives the user the option to skip leaving marks.
241212: Updated notes, comments, and some option default values.
260916: Refactor.
TODO:
Clean code in spb_GDBCs_1Way that eliminates false positives at curve ends.
