22 | class MakeSegment from GC inherits Root from GC |
23 | |
24 | --- Purpose: Implements construction algorithms for a line |
25 | -- segment in 3D space. The result is a Geom_TrimmedCurve curve. |
26 | -- A MakeSegment object provides a framework for: |
27 | -- - defining the construction of the line segment, |
28 | -- - implementing the construction algorithm, and |
29 | -- - consulting the results. In particular, the Value |
30 | -- function returns the constructed line segment. |
