Dear all

...... this is the way a non programmer works.. but it is painful. :-(

include <bosl2/std.scad>

$fn=100;
id=55; //Innendurchmesser
od=64; //Außendurchmesser
h=10; //Höhe über Alles
s=2; //Stärke

translate([0,0,h/2+s/2])
tube(h=h-s, or=id/2, wall=s);
difference()

{
cylinder(s,d=od);
    translate([-id/20.7,id/20.4,s0.5]) sphere(r=2);
    translate([-id/20.3,id/20.6,s0.5]) sphere(r=2);
    translate([id/20.4,id/20.5,s0.5]) sphere(r=2);
    translate([id/20.5,id/20.2,s0.5]) sphere(r=2);
    translate([id/20.2,-id/20.3,s0.5]) sphere(r=2);
    translate([-id/20.6,id/2*-0.3,s*0.5]) sphere(r=2);
}

How can I manage to get a valid array of coordinates which are all
within a defined circle with a diameter of n?

Many thanks in advance
Karl

P.S.
the goal is to print a kind of lid for different sizes of glasses... to
use them as vase for small flowers.

This line of code replaces your six lines to make the spheres:

for (angle = [0:60:300]) { rotate([0, 0, angle]) translate([-id/20.7,0,
0.5s]) sphere(2);}

I see you use BOSL2. Library is quite amazing. Spent the last 4 days trying to get my head around it and I feel I am barely touching the surface.

However, if you are you looking for a grid:

grid_copies(10, inside=circle(100)) cyl(d=5,h=1);

Or just along the edge?

arc_copies(d=100,n=40) circle(3);

if you just want the vectors:

path=arc(n=4,d=100,angle=360);
echo(path);

ECHO: [[50, 0], [-25, 43.3013], [-25, -43.3013], [50, 0]]

Do you want a set of random points? I wonder also if you should be using
cylinder instead of sphere to make the holes.

Hi Peter,

THIS is my favorite.... but I have a problem, as in these coordinates
the z-Achse is missing. So If I want to operate next with something like

path=arc(n=6,d=100,angle=360);

... it returns an array with x and y

/BUT to continue with /

for(i=[0:nz-1])

translate([path[i],0])

echo(path[i],0);
cylinder(d=2);

I need an array with a Z-Axis, too...

I receive an failure in "translate"

So my question is: How can I use the result from the path-Variable in
the first line?

Many thanks
Karl

if you just want the vectors:

 echo(path);

ECHO: [[50, 0], [-25, 43.3013], [-25, -43.3013], [50, 0]]

In BOSL2, to convert a path from XY 2D, to XYZ 3D, use p3d = path3d(p2d);.

Maybe missing curly brackets after the for() statement?

Hi Peter,

THIS is my favorite.... but I have a problem, as in these

with something like

... it returns an array with x and y

/BUT to continue with /

for(i=[0:nz-1])

translate([path[i],0])

echo(path[i],0);
cylinder(d=2);

I need an array with a Z-Axis, too...

I receive an failure in "translate"

So my question is: How can I use the result from the path-Variable
in the first line?

Many thanks

if you just want the vectors:

 echo(path);

ECHO: [[50, 0], [-25, 43.3013], [-25, -43.3013], [50, 0]]

I dont know about BOSL
but there are some syntax error which I can see and corrected below
Please check if this works

path=arc(6,55,360);
newpath = path3d(path);

for(i=[0:4])
{
echo (i);
echo(newpath[i]);
translate([newpath[i]]) cylinder(h=2,d=2);
