Hi all; I have two math functions from which I am interested to generate a CAD model. Attached is a picture for what I am looking for but not sure how to do it. <http://forum.openscad.org/file/t2047/cad_model.png> The border line equations are given (where x is inbetween 0 and 1) and the shaded black region is the one i want to generate the cad model. Also note that the third dimension does not matter for me as I am looking at a 2D case. It can be any flexible value. Thanks!! -- Sent from: http://forum.openscad.org/
