Re: OpenSCAD: How to make radially distributed holes

[Tyler Worman]

Offset one from the center. Then make a for loop using the value of the loop to multiply by the degree you rotate the holes.

for (j=[0:1:2]) {

rotate((j*360)/3)hole();

}

I'm making a custom vacuum tube socket design in OpenSCAD. I need to distribute a number of pin holes radially around the perimeter of the circular base. This link goes to an example of what I'm trying to make, although it isn't my design:

I can fiddle with manually placing the holes in the right spots, but that is error prone and time consuming. I'm sure OpenSCAD has a way to do this in a parameterized loop, or some other function, but I haven't been able to find it. Something like:

radial_holes(center, radius, angle) { ... }

Any pointers?

Thanks!

Ah! That did the trick. I'd played with rotate() a bit, but wasn't able to see how to get the correct axis to to be used. Thanks!
