23 | class MakePolygon from BRepLib inherits MakeShape from BRepLib |
24 | |
25 | ---Purpose: Class to build polygonal wires. |
26 | -- |
27 | -- A polygonal wire may be build from |
28 | -- |
29 | -- - 2,4,3 points. |
30 | -- |
31 | -- - 2,3,4 vertices. |
32 | -- |
33 | -- - any number of points. |
34 | -- |
35 | -- - any number of vertices. |
36 | -- |
37 | -- |
38 | -- When a point or vertex is added to the polygon if |
39 | -- it is identic to the previous point no edge is |
40 | -- built. The method added can be used to test it. |
