17class MakeWire from BRepBuilderAPI inherits MakeShape from BRepBuilderAPI

19 ---Purpose: Describes functions to build wires from edges. A wire can
20 -- be built from any number of edges.
21 -- To build a wire you first initialize the construction, then
22 -- add edges in sequence. An unlimited number of edges
23 -- can be added. The initialization of construction is done with:
24 -- - no edge (an empty wire), or
25 -- - edges of an existing wire, or
26 -- - up to four connectable edges.
27 -- In order to be added to a wire under construction, an
28 -- edge (unless it is the first one) must satisfy the following
29 -- condition: one of its vertices must be geometrically
30 -- coincident with one of the vertices of the wire (provided
31 -- that the highest tolerance factor is assigned to the two
32 -- vertices). It could also be the same vertex.
33 -- - The given edge is shared by the wire if it contains:
34 -- - two vertices, identical to two vertices of the wire
35 -- under construction (a general case of the wire closure), or
36 -- - one vertex, identical to a vertex of the wire under
37 -- construction; the other vertex not being
38 -- geometrically coincident with another vertex of the wire.
39 -- - In other cases, when one of the vertices of the edge
40 -- is simply geometrically coincident with a vertex of the
41 -- wire under construction (provided that the highest
42 -- tolerance factor is assigned to the two vertices), the
43 -- given edge is first copied and the coincident vertex is
44 -- replaced in this new edge, by the coincident vertex of the wire.
45 -- Note: it is possible to build non manifold wires using this construction tool.
46 -- A MakeWire object provides a framework for:
47 -- - initializing the construction of a wire,
48 -- - adding edges to the wire under construction, and
49 -- - consulting the result.

65 ---Purpose: Constructs an empty wire framework, to which edges
66 -- are added using the Add function.
67 -- As soon as the wire contains one edge, it can return
68 -- with the use of the function Wire.
69 -- Warning
70 -- The function Error will return

95 ---Purpose: Make a Wire from four edges.
96 ---Level: Public
97 returns MakeWire from BRepBuilderAPI;
98 ---Purpose: Constructs a wire
99 -- - from the TopoDS_Wire W composed of the edge E, or
100 -- - from edge E, or
101 -- - from two edges E1 and E2, or
102 -- - from three edges E1, E2 and E3, or
103 -- - from four edges E1, E2, E3 and E4.
104 -- Further edges can be added using the function Add.
105 -- Given edges are added in a sequence. Each of them
106 -- must be connectable to the wire under construction,
107 -- and so must satisfy the following condition (unless it is
108 -- the first edge of the wire): one of its vertices must be
109 -- geometrically coincident with one of the vertices of the
110 -- wire (provided that the highest tolerance factor is
111 -- assigned to the two vertices). It could also be the same vertex.
112 -- Warning
113 -- If an edge is not connectable to the wire under
114 -- construction it is not added. The function Error will
115 -- return BRepBuilderAPI_DisconnectedWire, the
116 -- function IsDone will return false and the function Wire
117 -- will raise an error, until a new connectable edge is added.

141 -- condition: one of its vertices must be geometrically coincident
142 -- with one of the vertices of the wire (provided that the highest
143 -- tolerance factor is assigned to the two vertices). It could also
