49 | ---Purpose: This method will be called when you want to share |
50 | -- the edges soon generated from an other face. |
51 | -- e.g. when two faces are tangents the common edge |
52 | -- will generate only one edge ( no pipe). |
53 | -- |
54 | -- The Map will be fill as follow: |
55 | -- |
56 | -- Created(E) = E' |
57 | -- with: E = an edge of <Face> |
58 | -- E' = the image of E in the offseting of |
59 | -- another face sharing E with a |
60 | -- continuity at least G1 |
