Data Structures

class BRepAlgoAPI_Section

Computes the intersection of two shapes or geometries.
Geometries can be surfaces of planes.
Geometries are converted to faces
When a geometry has been converted to
topology the created shape can be found using
the methods Shape1 and Shape2 inherited from the class BooleanOperation.
The result (Shape() method) is a compound containing
edges built on intersection curves.
By default, the section is performed immediatly in
class constructors, with default values :

geometries built are NOT approximated.
PCurves are NOT computed on both parts.
Example : giving two shapes S1,S2 accessing faces,
let compute the section edges R on S1,S2,
performing approximation on new curves,
performing PCurve on part 1 but not on part 2 :
Standard_Boolean PerformNow = Standard_False;
BRepBoolAPI_Section S(S1,S2,PerformNow);
S.ComputePCurveOn1(Standard_True);
S.Approximation(Standard_True);
S.Build();
TopoDS_Shape R = S.Shape();
On Null Shapes of geometries, NotDone() is called.
