Hi all,

I want to cut this cylinder
======================================
cylinder { <-5, 0, 0>, <0, 0, 0>, 1 }
======================================
It's inside an union with a cone to make an arrow.
The thing that I want to do, is cut it in the middle.
I thought using a plane, but I'm not sure if this is the best way to do it.
Any ideas?

All comments are welcome.

Regards,
Oleguer

Maybe something like this?:
======================================
#declare fletxa = object {
union {
cylinder { <-5, 0, 0>, <0, 0, 0>, 1 }
cone { <0, 0, 0>, 2, <3, 0, 0>, 0 }
pigment { rgb <0, 1.1, 0> }
scale <1, 1.6, 1>
rotate  170*y
rotate 25*x
rotate 45*z
translate <130.9, -23.5, 10>
no_shadow
}}

#declare tall= object { fletxa
clipped_by { plane { y, 10 } plane { -z, 3 }  }  }

object { tall translate <60, 0, 0> }
======================================

Regards,
Oleguer

I haven't read your other post, but yes, it is a good way to do it with a 
plane. Another way to do it would be with a box, remember to make it a bit 
bigger in the other axes so that you don't get a coincident surface problem.
