"""Provides GUI tools to convert polylines to B-splines and back.
|
|
|
|
These tools work on polylines and B-splines which have multiple points.
|
|
|
|
Essentially, the points of the original object are extracted
|
|
and passed to the `makeWire` or `makeBSpline` functions,
|
|
depending on the desired result.
