[Gmsh] rotational spline extrution.

[Jaco Du Plessis]

Dear gmsh team,

I Am trying to rotationally extrude a surface I have made between a line and spline. When i try I get the error, Could not find extruded vertex (..,..,..) i get this error about 700 times it seems that the edges are not being meshed for some reason. here is my script:

lc=0.1;
Point(1) = {0, 0,  0,  lc};
Point(2) = {0,0.25,-0.25,lc};
Point(3) = {0,0.5,-0.5,lc};
Point(4) = {0,0.25,-0.75,lc};
Point(5) = {0,0,-1.0,lc};
Spline(1)={1,2,3,4,5};
Line(2) = {5,1};
Line Loop(3)={1,2};
Plane Surface (4)={3};
Physical Surface("surf1") = {4} ;
out[] = Extrude{ {0,0,-1}, {0,0,-1.0}, 2*Pi} {
     Surface{4}; Layers{10,1}; Recombine;
};
Physical Volume(3)={out[1]};
Mesh.CharacteristicLengthExtendFromBoundary = 1;

I am using gmsh 2.8.4.

Any suggestions would be appreciated.

Regards,
Jaco.
