Hi Mike,
are you sure that the 4 points are really coplanar ? If yes, then it is a
numerical precision problem.
Whatever the reason, just replace "Plane Surface" by "Ruled Surface" and it
will be OK
Cheers,
Dave

Dear Gmsh users,
I define a simple plane surface with:
Point( 1001 ) = { -00000.250, +00000.000, +00000.000 };
Point( 1002 ) = { -00000.150, +00000.000, +00000.057 };
Point( 2001 ) = { -00000.206, +00000.100, +00000.036 };
Point( 2002 ) = { -00000.111, +00000.100, +00000.092 };
Line( 1011 ) = { 1001, 1002 };
Line( 1012 ) = { 1002, 2002 };
Line( 1013 ) = { 2002, 2001 };
Line( 1014 ) = { 2001, 1001 };
Line Loop( 1001 ) = { 1011, 1012, 1013, 1014 };
Plane Surface( 1001 ) = { 1001 };
but Gmsh reports the following error:
Plane Surface 1001 (...) is not a plane!
Error: Control Point 1001 = (-0.25,0,0), val = -0.00039966
Any suggestions?.
Thanks,
Mike.
