Hello Pilou,

the clone nodes doubles zylinder and rod and then there is a node that makes an intersection between them. If you get an solid -> "1" at the output it clashes:-) Then you can make an apply with diffrenent angles and you can create a solid, with respect to a clearence of couse, for a substraction body to make a clear off. But I do it neither - I only turn the knob and be happy:-)

Have a nice evening
Karsten
