rotate_extrude(convexity = 10, $fn = 100)

I'm trying to render the following 3D model. It takes too long and crashes often. Is this a known issue? Are there any known workarounds? I'’m using OpenSCAD 2014.03 on a 64 bit windows machine. Thanks, Arunanshu module bangle(n_rotations,degree, radius, width){ for (i=[0:360/n_rotations:360 - 360/n_rotations]) { // rotate about the Z axis rotate([0,0,i]) // rotate about the X axis rotate([degree,0,0]) // create a ring rotate_extrude(convexity = 10, $fn = 100) translate([radius, 0, 0]) circle(r = width, $fn = 100); } } //outer_ring_radius = 40; //inner_ring_radius = 37; //ring_height = 2; //n_rotations = 9; //degree = 20 bangle(9, 20, 32, 1); Sent from Surface

// create a ring

           rotate_extrude(convexity = 10, $fn = 100)
            translate([radius, 0, 0])
             circle(r = width, $fn = 100);

Your $fn=100 is a bit to large. My tip: always define fn1, fn2, at the beginning of the file and set it to lower values. Given your $fn values, try to estimate the number of facets your`ll produce.
