class FreeBounds from ShapeFix
|
|
|
|
---Purpose: This class is intended to output free bounds of the shape
|
|
-- (free bounds are the wires consisting of edges referenced by the
|
|
-- only face).
|
|
-- For building free bounds it uses ShapeAnalysis_FreeBounds class.
|
|
-- This class complements it with the feature to reduce the number
|
|
-- of open wires.
|
|
-- This reduction is performed with help of connecting several
|
|
-- adjacent open wires one to another what can lead to:
|
|
-- 1. making an open wire with greater length out of several
|
|
-- open wires
|
|
-- 2. making closed wire out of several open wires
|
|
--
|
|
-- The connecting open wires is performed with a user-given
|
|
-- tolerance.
|
|
--
|
|
-- When connecting several open wires into one wire their previous
|
|
-- end vertices are replaced with new connecting vertices. After
|
|
-- that all the edges in the shape sharing previous vertices inside
|
|
-- the shape are updated with new vertices. Thus source shape can
|
|
-- be modified.
|
|
--
|
|
-- Since interface of this class is the same as one of
|
|
-- ShapeAnalysis_FreeBounds refer to its CDL for details.
