| 24 | |
| 25 | ---Purpose: class for the creation of Offseting. |
| 26 | |
| 27 | uses |

| 29 | Status from BRepOffset, |
| 30 | Shape from TopoDS, |
| 31 | Face from TopoDS, |
| 32 | Edge from TopoDS, |
| 33 | Vertex from TopoDS, |

| 54 | JoinType : JoinType from GeomAbs = GeomAbs_Arc) |
| 55 | ---Purpose: This method will be called when you want to share |
| 56 | -- the edges soon generated from an other face. |
| 57 | -- e.g. when two faces are tangents the common edge |
| 58 | -- will generate only one edge ( no pipe). |
| 59 | -- |
| 60 | -- The Map will be fill as follow: |
| 61 | -- |
| 62 | -- Created(E) = E' |
| 63 | -- with: E = an edge of <Face> |
| 64 | -- E' = the image of E in the offseting of |
| 65 | -- another face sharing E with a |
| 66 | -- continuity at least G1 |
