BRepOffsetAPI_MakeEvolved Class Reference

Describes functions to build evolved shapes.
An evolved shape is built from a planar spine (face or
wire) and a profile (wire). The evolved shape is the
unlooped sweep (pipe) of the profile along the spine.
Self-intersections are removed.
A MakeEvolved object provides a framework for:

 These constructors construct an evolved shape by sweeping the profile
Profile along the spine Spine.
The profile is defined in a coordinate system R.
The coordinate system is determined by AxeProf:

const BRepFill_EvolvedEvolved () const
virtual void Build ()
 Builds the resulting shape (redefined from MakeShape).

const TopTools_ListOfShapeGeneratedShapes (const TopoDS_Shape &SpineShape, const TopoDS_Shape &ProfShape) const
 Returns the shapes created from a subshape
<SpineShape> of the spine and a subshape
<ProfShape> on the profile.

const TopoDS_ShapeTop () const
 Return the face Top if <Solid> is True in the constructor.

const TopoDS_ShapeBottom () const
 Return the face Bottom if <Solid> is True in the constructor.

  • if AxeProf is true, R is the global coordinate system,
  • if AxeProf is false, R is computed so that:
    • its origin is given by the point on the spine which is
      closest to the profile,
    • its "X Axis" is given by the tangent to the spine at this point, and
  • its "Z Axis" is the normal to the plane which contains the spine.
    The position of the profile at the current point of the
    spine is given by making R coincident with the local
    coordinate system given by the current point, the
    tangent vector and the normal to the spine.
    Join defines the type of pipe generated by the salient
    vertices of the spine. The default type is GeomAbs_Arc
    where the vertices generate revolved pipes about the
    axis passing along the vertex and the normal to the
    plane of the spine. At present, this is the only
    construction type implemented.
