I would like to use a torus with minor radius > major radius to connect 2
cylinder but here is the result when the minor radius > major radius.
The whole is not always visible.
Do you experimente this situation ?
Is there a way to avoid this whole ?
I post this message at ninaries images because for me it is easiest to to
explain my problem with an image
default { texture { pigment { rgb <1,0,0> } }}
background { color <0.737255, 0.737255, 0.870588> }

I don't really understand your problem here, but myabe this is the sort
of thing you're looking for, it takes a half torus and connects it to a
cylinder using two more torus sections:
union{
difference{
torus{2.5, 0.2}
box{<3,0.5,0>, <-3,-0.5,-3>}
} // End of Difference
#local Dummy_Corner_Arc =
difference{
torus{0.5, 0.2}
box{<1,0.5,0>,<-1,-0.5,-1>}
box{<0,0.5,1>,<1,-0.5,-1>}
} // End of Difference.
object{Dummy_Corner_Arc rotate y*-90 translate x*-2}
object{Dummy_Corner_Arc rotate y*180 translate x*2}
cylinder{<-2,0,-0.5>,<2,0,-0.5>,0.2 }
texture{pigment{Dummy_Body_Colour1}
finish{Dummy_Body_Finish}
}
scale <0.5,0.75,0.65>
rotate y*90
translate x*1
} // End of Union.
You'll have to change the texture to render this, hope it helps.

You are witnessing a bug, I believe, with the torus object in POV-Ray
version 3.1g (also MegaPOV 0.7). What happens is that the inside/outside
becomes confused.

Thank you for your answer, so i have to find a way that doesn't use such a
torus.
Thank for all

For what it's worth, this bug will be fixed in 3.5.
