Detailed 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 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.

Implementation.

Returns
brep.m_C3[] index of the 3d curve geometry used by this edge or -1.

◆ IsValid()

bool ON_BrepEdge::IsValid ( class ON_TextLog text_log = nullptr) const
overridevirtual

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 englis description of the reason the object is not valid is appened to the log. The information appended to text_log is suitable for
lowlevel debugging purposes by programmers and is not intended to be useful as a high level user interface tool.
Returns
table true object is valid false object is invalid, uninitialized, etc.

Reimplemented from ON_Object.

◆ ObjectType()

ON::object_type ON_BrepEdge::ObjectType ( ) const
overridevirtual

Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on.

Returns

ON::object_type enum value.

The default implementation of this virtual function returns ON::unknown_object_type

Returns
Number of trims attached to this edge.

◆ UnsetPlineEdgeParameters()

void ON_BrepEdge::UnsetPlineEdgeParameters ( )
