 --
-Reflect lines are represented by edges in 3d.
+This algorithm computes the projection of the shape in the ViewDir direction.
+If OnShape is False(default), the returned edges are flat on the XY plane defined by
+ViewPos(origin) and UpDir(up direction).
+If OnShape is True, the returned edges are the corresponding 3D reflect lines located on the shape.
+EdgeType is a string defining the type of result edges :
+- IsoLine : isoparametric line
+- OutLine : outline (silhouette) edge
+- Rg1Line : smooth edge of G1-continuity between two surfaces
+- RgNLine : sewn edge of CN-continuity on one surface
+- Sharp : sharp edge (of C0-continuity)
+If Visible is True (default), only visible edges are returned.
+If Visible is False, only invisible edges are returned.
