Dear all Is it possible to change the clock (direction) from this formula poly=circle(5); spiral_sweep(poly, h=200, r=50, turns=8, $fn=36, orient=LEFT); so that the spiral goes clockwise or counter clickwise? many thanks in advance. Karl P.S. The orientation-tag does not this job... ;-)

Does setting turns=-8 do what you want?

No need. As Adrian pointed out, 'turns = -8' does it.
