| | 19 | ---Purpose: This class compute elemenary offset surface. |
| | 20 | -- Evaluate the offset generated : |
| | 21 | -- 1 - from a face. |
| | 22 | -- 2 - from an edge. |
| | 23 | -- 3 - from a vertex. |

| | 53 | -- the edges soon generated from an other face. |
| | 54 | -- e.g. when two faces are tangents the common edge |
| | 55 | -- will generate only one edge ( no pipe). |

| | 57 | -- The Map will be fill as follow: |
| | 58 | -- |
| | 59 | -- Created(E) = E' |
| | 60 | -- with: E = an edge of <Face> |
| | 61 | -- E' = the image of E in the offseting of |
| | 62 | -- another face sharing E with a |
| | 63 | -- continuity at least G1 |
