BRepBuilderAPI_MakeEdge Class Reference

Provides methods to build edges.

The methods have the following syntax, where
TheCurve is one of Lin, Circ, ...

Create(C : TheCurve)

Makes an edge on the whole curve. Add vertices
on finite curves.

Create(C : TheCurve; p1,p2 : Real)

Make an edge on the curve between parameters p1
and p2. if p2 < p1 the edge will be REVERSED. If
p1 or p2 is infinite the curve will be open in
that direction. Vertices are created for finite
values of p1 and p2.

Create(C : TheCurve; P1, P2 : Pnt from gp)

Make an edge on the curve between the points P1
and P2. The points are projected on the curve
and the previous method is used. An error is
raised if the points are not on the curve.

Create(C : TheCurve; V1, V2 : Vertex from TopoDS)

Make an edge on the curve between the vertices
V1 and V2. Same as the previous but no vertices
are created. If a vertex is Null the curve will
be open in this direction.

• a 3D curve C as the support (geometric domain) of the edge,
  
• two vertices V1 and V2 to limit the curve (definition of the restriction of
  the edge), and
  
• two real values p1 and p2 which are the parameters for the vertices V1 and V2
  on the curve.
  The curve may be defined as a 2d curve in the parametric space of a surface: a
  pcurve. The surface on which the edge is built is then kept at the level of the edge.
  The default tolerance will be associated with this edge.
  Rules applied to the arguments:
  For the curve:
  
• The curve must not be a 'null handle'.
  
• If the curve is a trimmed curve the basis curve is used.
  For the vertices:
  
• Vertices may be null shapes. When V1 or V2 is null the edge is open in the
  corresponding direction and the parameter value p1 or p2 must be infinite
  (remember that Precision::Infinite() defines an infinite value).
  
• The two vertices must be identical if they have the same 3D location.
  Identical vertices are used in particular when the curve is closed.
  For the parameters:
  
• The parameters must be in the parametric range of the curve (or the basis
  curve if the curve is trimmed). If this condition is not satisfied the edge is not
  built, and the Error function will return BRepAPI_ParameterOutOfRange.
  
• Parameter values must not be equal. If this condition is not satisfied (i.e.
  if | p1 - p2 | ) the edge is not built, and the Error function will return
  BRepAPI_LineThroughIdenticPoints.
  Parameter values are expected to be given in increasing order:
  C->FirstParameter()
  
• If the parameter values are given in decreasing order the vertices are switched,
  i.e. the "first vertex" is on the point of parameter p2 and the "second vertex" is
  on the point of parameter p1. In such a case, to keep the original intent of the
  construction, the edge will be oriented "reversed".
  
• On a periodic curve the parameter values p1 and p2 are adjusted by adding or
  subtracting the period to obtain p1 in the parametric range of the curve, and p2]
  such that [ p1 , where Period is the period of the curve.
  
• A parameter value may be infinite. The edge is open in the corresponding
  direction. However the corresponding vertex must be a null shape. If this condition
  is not satisfied the edge is not built, and the Error function will return
  BRepAPI_PointWithInfiniteParameter.
  
• The distance between the vertex and the point evaluated on the curve with the
  parameter, must be lower than the precision of the vertex. If this condition is not
  satisfied the edge is not built, and the Error function will return
  BRepAPI_DifferentsPointAndParameter.
  Other edge constructions
  
• The parameter values can be omitted, they will be computed by projecting the
  vertices on the curve. Note that projection is the only way to evaluate the
  parameter values of the vertices on the curve: vertices must be given on the curve,
  i.e. the distance from a vertex to the curve must be less than or equal to the
  precision of the vertex. If this condition is not satisfied the edge is not built,
  and the Error function will return BRepAPI_PointProjectionFailed.
  
• 3D points can be given in place of vertices. Vertices will be created from the
  points (with the default topological precision Precision::Confusion()).
  Note:
  
• Giving vertices is useful when creating a connected edge.
  
• If the parameter values correspond to the extremities of a closed curve,
  points must be identical, or at least coincident. If this condition is not
  satisfied the edge is not built, and the Error function will return
  BRepAPI_DifferentPointsOnClosedCurve.
  
• The vertices or points can be omitted if the parameter values are given. The
  points will be computed from the parameters on the curve.
  The vertices or points and the parameter values can be omitted. The first and last
  parameters of the curve will then be used.
