Hello all, I'm a newbe on openscad. I want to copy a cylinder around Z then copy it upwards. That's working but I cannot get a twist in. The first cylinder is: module Zylinder () { rotate ([90,0,0]) cylinder (h = 30, r=3 , $fn=6); } Then I copy it around Z: module FirstLayer() { for(a=[0 : 90 : 270]) rotate(a) Zylinder(); } Until here it is working. I have 4 Cylinders like a cross. But how can I copy the whole cross up let's say 20mm and twist it let's say 30° so I have the copied one 30° "twisted"?

Translate the second up (+z) 20mm   translate(0,0,20); On 2020-04-19 9:43 a.m., Snörre wrote: > Hello all, > I'm a newbe on openscad. > I want to copy a cylinder around Z then copy it upwards.

Sorry, I forgot to add this. for(z=[ 0 : 10 : 10 ]) translate([0,0,z]) for(a=[0 : 90 : 270 ]) rotate(a) rotate ([90,0,0]) cylinder (h = 30, r=3, $fn=6); But on the "translated" I would like to have an additional rotation around "Z" Something like an additional "rotate(b)" but then the lowest cross is also getting this copy.

Remember: when the emperor looks naked, the emperor *is* naked, the truth and a lie are not "sort-of the same thing" and there is no aspect, no facet, no moment of life that can't be improved with pizza. -Daria Morgendorffer

YESSSSSSS !!!!!!! for(z=[ 0 : 10 : 60 ]) translate([0,0,z]) for(a=[0 : 90 : 270 ]) rotate(a+z) rotate ([90,0,0]) cylinder (h = 30, r=3, $fn=6); Now it looks like this: Am Sonntag, 19.
