This code seems to do the same:
#declare OneSide =
intersection {
torus {
1, 0.08
translate <-0.4, 0, 0>
}
box {
<0, -0.08, 0>, <0.68, 0.08, 1.08>
}
}
#declare GothArch =
union {
object {
OneSide
}
object {
OneSide
rotate 180*z // Or do this: scale <-1, 1, 1>
}
rotate -90*x
}
object {
GothArch
pigment { Red }
}
