How to translate a complex object ?
I want to translate an object but I can't do it by doing
translate([0,0,-12]) {
{
...
}
}
Then I don't know how to do it for this script :
/* 'Nut Job' nut, bolt, washer and threaded rod factory by Mike Thompson
1/12/2013, Thingiverse: mike_linus
- v2 8/12/2013 - added socket head types
- v3 2/11/2014 - adjusted wing nut algorithm for better behaviour with
unusual nut sizes and added ISO262 metric references - This script generates nuts, bolts, washers and threaded rod using the
library - script: polyScrewThead.scad (modified/updated version
polyScrewThread_r1.scad) - http://www.thingiverse.com/thing:8796, CC Public Domain
- Defaults are for a 8mm diameter bolts, rod, matching nuts and wing nuts
that work well together - without cleanup or modification. Some default parameters such as the nut
outer diameter are deliberately - altered to produce a snug fit that can still be hand tightened. This may
need to be altered - depending on individual printer variances, slicing tools, filament etc.
Suggest printing a matching - bolt and nut and adjusting as necessary. Note: slow print speeds, low
temperatures and solid - fill are recommended for best results.

Thanks you very much !
When I add :
use <polyScrewThread_r1.scad>
translate([0,0,-12]) hex_nut(24,8,4,55,15,0.5);
It designs 2 objects. How can I remove the centered one ?

You don't add it, you put those lines a separate file.

It will only add one object.
Note: you don’t need anything except those two lines in your scad file.
