Have a look at the two different roof() calls in the simplistic piece of code. Uncommenting the "straight" option seems to create a CGAL problem with F6. I tracked down this effect from a more complex code for a logo import (SVG) that renders fine with F6 but seems to ignore the cube in straight mode only. difference() { //  roof(method = "voronoi")   roof(method = "straight")   text("hallo world");   translate([-1,-1, .2]) cube([80, 12, 1]); } Rudolf
