Subject: Fix associated with bug #0022843: EDF GEOM: [HYDRO] Polyline using a former polyline.
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=ecdebda9c3214c4f7b684367336c2eb37da2cf26;p=modules%2Fgeom.git

Fix associated with bug #0022843: EDF GEOM: [HYDRO] Polyline using a former polyline.
Modification is to consider last point of unclosed polyline, and disposals last point of closed spline as it coincides with the first.
