class MakeSegment from GCE2d inherits Root from GCE2d
|
|
|
|
---Purpose: Implements construction algorithms for a line
|
|
-- segment in the plane. The result is a
|
|
-- Geom2d_TrimmedCurve curve.
|
|
-- A MakeSegment object provides a framework for:
|
|
-- - defining the construction of the line segment,
|
|
-- - implementing the construction algorithm, and
|
|
-- - consulting the results. In particular, the Value
|
|
-- function returns the constructed line segment.
