static Standard_Integer | EdgesToWires (const TopoDS_Shape &theEdges, TopoDS_Shape &theWires, const Standard_Boolean theShared=Standard_False, const Standard_Real theAngTol=1.e-8) |
Creates planar wires from the given edges. The input edges are expected to be planar. And for the performance sake the method does not check if the edges are really planar. Thus, the result wires will also be not planar if the input edges are not planar. The edges may be not shared, but the resulting wires will be sharing the coinciding parts and intersecting parts. The output wires may be non-manifold and contain free and multi-connected vertices. Parameters: <theEdges> - input edges; <theWires> - output wires; <theShared> - boolean flag which defines whether the input edges are already shared or have to be intersected; <theAngTol> - the angular tolerance which will be used for distinguishing the planes in which the edges are located. Default value is 1.e-8 which is used for intersection of planes in IntTools_FaceFace. Method returns the following error statuses: 0 - in case of success (at least one wire has been built); 1 - in case there are no edges in the given shape; 2 - sharing of the edges has failed.

static Standard_Boolean | WiresToFaces (const TopoDS_Shape &theWires, TopoDS_Shape &theFaces, const Standard_Real theAngTol=1.e-8) |
Creates planar faces from given planar wires. The method does not check if the wires are really planar. The input wires may be non-manifold but should be shared. The wires located in the same planes and included into other wires will create holes in the faces built from outer wires. The tolerance values of the input shapes may be modified during the operation due to projection of the edges on the planes for creation of 2D curves. Parameters: <theWires> - the given wires; <theFaces> - the output faces; <theAngTol> - the angular tolerance for distinguishing the planes in which the wires are located. Default value is 1.e-8 which is used for intersection of planes in IntTools_FaceFace. Method returns TRUE in case of success, i.e. at least one face has been built. More... | |

Classifies the faces <theFaces> relatively solids <theSolids>. The IN faces for solids are stored into output data map <theInParts>.
The map <theSolidsIF> contains INTERNAL faces of the solids, to avoid their additional classification.
Firstly, it checks the intersection of bounding boxes of the shapes. If the Box is not stored in the <theShapeBoxMap> map, it builds the box. If the bounding boxes of solid and face are interfering the classification is performed.
It is assumed that all faces and solids are already intersected and do not have any geometrically coinciding parts without topological sharing of these parts

Creates planar wires from the given edges.
The input edges are expected to be planar. And for the performance sake the method does not check if the edges are really planar.
Thus, the result wires will also be not planar if the input edges are not planar.
The edges may be not shared, but the resulting wires will be sharing the coinciding parts and intersecting parts.
The output wires may be non-manifold and contain free and multi-connected vertices.
Parameters: <theEdges> - input edges;
<theWires> - output wires;
<theShared> - boolean flag which defines whether the input edges are already shared or have to be intersected;
<theAngTol> - the angular tolerance which will be used for distinguishing the planes in which the edges are located. Default value is 1.e-8 which is used for intersection of planes in IntTools_FaceFace.
Method returns the following error statuses:
0 - in case of success (at least one wire has been built);
1 - in case there are no edges in the given shape;
2 - sharing of the edges has failed.

Creates planar faces from given planar wires.
The method does not check if the wires are really planar.
The input wires may be non-manifold but should be shared.
The wires located in the same planes and included into other wires will create holes in the faces built from outer wires.
The tolerance values of the input shapes may be modified during the operation due to projection of the edges on the planes for creation of 2D curves.
Parameters: <theWires> - the given wires;
<theFaces> - the output faces;
<theAngTol> - the angular tolerance for distinguishing the planes in which the wires are located. Default value is 1.e-8 which is used for intersection of planes in IntTools_FaceFace.
Method returns TRUE in case of success, i.e. at least one face has been built.
