<p><code>rotate()</code> always rotates around the origin of the object following it.
What you can do is to move your cylinder <em>away</em> from the origin, like this:</p>

<pre><code>rotate(a=[90,0,0]) {
  translate([0,10,0]) cylinder(h=10,r1=10,r2=10);
}
</code></pre>

<p>How to make it rotate around its edge?</p>

# How to specify rotation origin in openscad

(Asked by: username_0 on 2019-02-03)

OpenSCAD has rotate function which rotates the body around its origin axis.
Is there a way to specify an arbitrary axis?
For example, this rotates a cylinder around its center:
rotate(a=[90,0,0]) {
  cylinder(h=10,r1=10,r2=10);
}

How to make it rotate around its edge?

You can use the following module in your code to achieve what you wish:
module myrotate(a, orig) {
    translate(orig)
    rotate(a)
    translate(-orig)
    children();
}

myrotate([0,0,90], [0, 10, 0]) {
    cube([10, 10, 25]);
}

myrotate([0,0,-90], [0, 10, 0]) {
    cube([10, 10, 25]);
}

color([1, 0, 0])
cube([10, 10, 25]);
