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:

ShapeFix_FreeBounds (const TopoDS_Shape &shape, const Standard_Real sewtoler, const Standard_Real closetoler, const Standard_Boolean splitclosed, const Standard_Boolean splitopen) | |
Builds forecasting free bounds of the <shape> and connects open wires with tolerance <closetoler>. <shape> should be a compound of faces. Tolerance <closetoler> should be greater than tolerance <sewtoler> used for initializing sewing analyzer, otherwise connection of open wires is not performed. | |
ShapeFix_FreeBounds (const TopoDS_Shape &shape, const Standard_Real closetoler, const Standard_Boolean splitclosed, const Standard_Boolean splitopen) | |
Builds actual free bounds of the <shape> and connects open wires with tolerance <closetoler>. <shape> should be a compound of shells. | |
const TopoDS_Compound & | GetClosedWires () const |
Returns compound of closed wires out of free edges. | |
const TopoDS_Compound & | GetOpenWires () const |
Returns compound of open wires out of free edges. | |
const TopoDS_Shape & | GetShape () const |
Returns modified source shape. |
1. making an open wire with greater length out of several <br> open wires <br> 2. making closed wire out of several open wires <br>
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.
