[Gmsh] BUG (Draw): Re: Sleep command.

[Maka Mohu]

Thanks to all for suggestions. Richard trick worked. According to Draw
command description, it seems to be a BUG. Draw does not update the scene.
This a working example. Have a nice day!

--------------------------------------------------
lc = 0.2;
Point(1) = {0,0,0,lc};
Point(2) = {1,0,0,lc};
Point(6) = {0,0,3,lc};
Line(1) = {1,2};
Line(2) = {2,6};
Line(3) = {6,1};
Line Loop(4) = {2,3,1};
Plane Surface(5) = {4};

Extrude {{0,0,1}, {0,0,0}, Pi/2} { Surface{5}; }
Extrude {{0,0,1}, {0,0,0}, Pi/2} { Surface{17}; }

// added lines:
Draw;
// needed trick because Draw does not update the scene (possible BUG).
Print "dummy_view.jpg";
Sleep 5;

Extrude {{0,0,1}, {0,0,0}, Pi/2} { Surface{29}; }
Extrude {{0,0,1}, {0,0,0}, Pi/2} { Surface{41}; }

Best regards,
Maka
