Subject: Issue #2299: Wrong face support of sketch in script from python dump
X-Git-Tag: V_2.10.0RC~142
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=b375a060800d22b49e4a6752bcdab09917a69cfe;p=modules%2Fshaper.git

Issue #2299: Wrong face support of sketch in script from python dump

Use BRepTools_WireExplorer instead of TopExp_Explorer when building sketch face, because it takes into account the connectivity of the wire.
