I have a relatively simple model. Preview (F5) is done in less than a second.
Rendering (F6) does not finish overnight.
It fails.
Last time after many attempts and changes in the preferences It stoped with
the error:
Rendering canceled.
UI-WARNING: No top-level geometry to render.
This is my code:
//Ellipse Pendant.
//================

module cir(){
r=0.8;
$fn=32;
translate([-3.5,3.5,0])
rotate_extrude(convexity = 10)
translate([2, 0, 0])
circle(r);

translate([3.5,3.5,0])
rotate_extrude(convexity = 10)
translate([2, 0, 0])
circle(r);

translate([0,-1.8,0])
rotate_extrude(convexity = 10)
translate([2.4, 0, 0])
circle(r);
}
module glob(){
r=0.8;
$fn=32;
for (i=[0:360/6:360]){
rotate([i,0,0])
rotate_extrude(convexity = 10)
translate([10, 0, 0])
circle(r);}

for (i=[0:360/8:360]){
rotate([0,0,i])
rotate([90,0,0])
rotate_extrude(convexity = 10)

}
