    // construct a box
    var box = occ.makeBox([0, 0, 0], [100, 100, 50]);
     
    // construct a cylinder
    var cyl = occ.makeCylinder([50, 50, -10], [50, 50, 60], 40);
     
    // cut the box with cylinder
    box = occ.cut(box, cyl);
     
    // save result to a STEP file
    occ.writeSTEP("somefile.step", box);
