Well that's less blocky but its too big and I also want a circle extruded
along an arc. I've been looking around and it looks like sweep() is what
I'm looking for, […]
Sweep is a bit general and probably requires too much configuration to fit your needs perfectly.
Currently, the best solution I can think of is to just intersect your 360 degree rotation volume with a wedge.
Here’s a quick starting point:
module rotate_extrude_angle(angle, size) {
module pie(a) {
r=sqrt(2);
hull() polyhedron(points=[[0,0,-r], [r,0,-r], [rcos(a),rsin(a),-r],[0,0,r], [r,0,r], [rcos(a),rsin(a),r]], faces=[[0,1,2,3,4,5]]);
}
intersection() {
scale(size) pie(angle);
rotate_extrude() children();
}
}
rotate_extrude_angle(45, 13) translate([8,0]) circle(5);
