Hello everyone, im new to this forum and new to OpenSCAD program. Awsome program. First, i tried this: cylinder_array(21,5) cylinder(r=2, h=10); module cylinder_array( count, distance ){ for ( i = [0:1:count-1] ){ translate([distance*i,0,0]) children(); } } Then i wanted to copy that row into serveal rows. I didn't had a clue and i did like this: translate ([-0,0,0]) cylinder_array(21,5) cylinder(r=2, h=10); translate ([-0,5,0]) cylinder_array(21,5) cylinder(r=2, h=10); translate ([-0,10,0]) cylinder_array(21,5) cylinder(r=2, h=10); translate ([-0,15,0]) cylinder_array(21,5) cylinder(r=2, h=10); translate ([-0,20,0]) cylinder_array(21,5) cylinder(r=2, h=10); translate ([-0,25,0]) cylinder_array(21,5) cylinder(r=2, h=10); translate ([-0,30,0]) cylinder_array(21,5) cylinder(r=2, h=10); translate ([-0,35,0]) cylinder_array(21,5) cylinder(r=2, h=10); module cylinder_array( count, distance ){ for ( i = [0:1:count-1] ){ translate([distance*i,0,0]) children(); } } Cool i was thinking, but knew there a better way of doing this. If im gonna make serveal of these the code will be long and messy. Not good. Then i was thinking, hmm how? I tried this: cylinder_array(21,5,25) cylinder(r=2, h=10); module cylinder_array( count, distance, rows ){ for ( i = [0:1:count-1] ){ for ( h = [0:1:rows-1]){ translate([0,distance*i,0]) translate([rows+distance*h,0,0]) children(); } } } Wow, i almost can taste it, much much less code but i dont think this is enterily correct either. I see the whole thing moved away from origin: 0,0 .. why? I know iv done something wrong here. Anyone out there can help me a little on the road? -- View this message in context: http://forum.openscad.org/Cylinder-array-count-distance-rows-tp21740.html Sent from the OpenSCAD mailing list archive at Nabble.com.

It is translated from the origin because you added rows to distance * h. Here is a corrected version with even less code: cylinder_array(21,5,25) cylinder(r=2, h=10); module cylinder_array( count, distance, rows ) for (i = [0 : count - 1], h = [0 : rows-1]) translate([distance * h, distance * i, 0]) children(); On 25 June 2017 at 13:36, Droidene <koford@gmail.com> wrote: > Hello everyone, im new to this forum and new to OpenSCAD program. > Awsome program. > > First, i tried this: > > cylinder_array(21,5) cylinder(r=2, h=10); > > module cylinder_array( count, distance ){ > for ( i = [0:1:count-1] ){ > translate([distance*i,0,0]) > children(); > } > } > > Then i wanted to copy that row into serveal rows. > I didn't had a clue and i did like this: > > translate ([-0,0,0]) cylinder_array(21,5) cylinder(r=2, h=10); > translate ([-0,5,0]) cylinder_array(21,5) cylinder(r=2, h=10); > translate ([-0,10,0]) cylinder_array(21,5) cylinder(r=2, h=10); > translate ([-0,15,0]) cylinder_array(21,5) cylinder(r=2, h=10); > translate ([-0,20,0]) cylinder_array(21,5) cylinder(r=2, h=10); > translate ([-0,25,0]) cylinder_array(21,5) cylinder(r=2, h=10); > translate ([-0,30,0]) cylinder_array(21,5) cylinder(r=2, h=10); > translate ([-0,35,0]) cylinder_array(21,5) cylinder(r=2, h=10); > > module cylinder_array( count, distance ){ > for ( i = [0:1:count-1] ){ > translate([distance*i,0,0]) > children(); > } > } > > Cool i was thinking, but knew there a better way of doing this.

Ahh of course, thank you. It make all sense, awsome. -- View this message in context: http://forum.openscad.org/Cylinder-array-count-distance-rows-tp21740p21742.html Sent from the OpenSCAD mailing list archive at Nabble.com.
