Detailed Description
Description: Brep edge information is stored in ON_BrepEdge classes. ON_Brep.m_E[] is an array of all the edges in the brep.
An ON_BrepEdge is derived from ON_CurveProxy so the edge can supply easy to use evaluation tools via the ON_Curve virtual member functions.
Note well that the domains and orientations of the curve m_C3[edge.m_c3i] and the edge as a curve may not agree. April 24, 2017 Dale Lear ON_Curve::Trim(const ON_Interval&) is a virtual function and ON_BrepEdge derives from ON_CurveProxy which derives from ON_Curve. The ON_Brep::Trim(int) function was added and mistakenly named "Trim". This all happened about twenty years ago.
Both the virtual ON_Curve::Trim(const ON_Interval&) and ON_BrepEdge::Trim(int) functions are widely used. At some point the functionON_Brep::Trim() will be deprecated and the 4263 warning ON_Brep::Trim(int) generates will be disabled for the definition of class ON_BrepEdge. In version 7, ON_Brep::Trim(int) will be deleted and the warning will no longer be disabled.

/ virtual ON_Curve::SetEndPoint override bool SetEndPoint( ON_3dPoint end_point ); Description: For a manifold, non-boundary edge, decides whether or not the two surfaces on either side meet smoothly. Parameters: angle_tolerance - [in] used to decide if surface normals on either side are parallel. Returns: true if edge is manifold, has exactly 2 trims, and surface normals on either side agree to within angle_tolerance.
◆ IsValid()
|
overridevirtual |
Description: Tests an object to see if its data members are correctly initialized. Parameters: text_log - [in] if the object is not valid and text_log is not nullptr, then a brief english description of the reason the object is not valid is appended to the log. The information appended to text_log is suitable for low-level debugging purposes by programmers and is not intended to be useful as a high level user interface tool. Returns: @untitled table true object is valid false object is invalid, uninitialized, etc.

virtual ON_Object function The ON_BrepEdge override returns ON::curve_object.

◆ operator=()
| ON_BrepEdge& ON_BrepEdge::operator= | ( | const ON_BrepEdge & | ) |
◆ ProxyBrepSubDEdgeId()
| unsigned int ON_BrepEdge::ProxyBrepSubDEdgeId | ( | ) | const |
Returns: If this edge is part of a brep created by ON_SubD::ProxyBrep(), then the subd component id of the corresponding SubD edge is returned. Otherwise 0 is returned.
◆ Read()

virtual ON_Object::Read() override

◆ Reverse()

virtual ON_Curve::Reverse override
Implements ON_Curve.
◆ SizeOf()

virtual ON_Object::SizeOf override
Reimplemented from ON_Object.
◆ Trim()
| ON_BrepTrim* ON_BrepEdge::Trim | ( | int | eti | ) | const |
Parameters: eti - [in] index into the edge's m_ti[] array. Returns: The trim brep.m_T[edge.m_ti[eti]]; Remarks: This version of "Trim" hides the virtual function ON_CurveProxy::Trim(const ON_Interval&), which is a good thing. Special care must be taken when changing the geometry of a brep edge to insure vertex, trim, and edge information remains valid.
◆ TrimCount()
| int ON_BrepEdge::TrimCount | ( | ) | const |
Returns: Number of trims attached to this edge.
◆ UnsetPlineEdgeParameters()
| void ON_BrepEdge::UnsetPlineEdgeParameters | ( | ) |
Description: When an edge is modified, the m_pline[].e values need to be set to ON_UNSET_VALUE by calling UnsetPlineEdgeParameters().
◆ Vertex()
| ON_BrepVertex* ON_BrepEdge::Vertex | ( | int | evi | ) | const |
Parameters: evi - [in] 0 or 1 Returns: Brep vertex at specified end of the edge.

Union available for application use. The constructor zeros m_edge_user. The value is of m_edge_user is not saved in 3DM archives and may be changed by some computations.

◆ m_tolerance
| double ON_BrepEdge::m_tolerance = ON_UNSET_VALUE |
accuracy of edge curve (>=0.0 or ON_UNSET_VALUE)
A value of ON_UNSET_VALUE indicates that the tolerance should be computed.
The maximum distance from the edge's 3d curve to any surface of a face that has this edge as a portion of its boundary must be <= this tolerance.
◆ m_vi
| int ON_BrepEdge::m_vi[2] |
indices of starting/ending vertex
For closed edges, m_vi[0] = m_vi[1] and m_edge_index appears twice in the m_V[m_vi[0]].m_ei[] array. The first occurrence of m_edge_index in m_V[m_vi[0]].m_ei[] is for the closed edge starting the vertex. The second occurrence of m_edge_index in m_V[m_vi[0]].m_ei[] is for the closed edge ending at the vertex. C.f. ON_Brep::Next/PrevEdge().
