Each p inside braces is a new one in a scope that lasts to the closing brace. That is why it has no effect. But also in OpenSCAD a variable can only have one value and that is the last value assigned. This is the syntax you need: module prisme(x, y, z, sens){ p = sens == 1 ? [ [0,0,0],[x,0,0],[x,y,0],[0,y,0],[0,y,z],[x,y,z] ] : sens == -1 ? [ [0,0,0],[x,0,0],[x,y,0],[0,y,0],[0,y,-z],[x,y,-z] ] : sens == 2 ? [ [ [0,0,0],[x,0,0],[x,y,0],[0,y,0],[0,0,z],[x,0,z] ] : sens == -2 ? [ [0,0,0],[x,0,0],[x,y,0],[0,y,0], [0,0,-z],[x,0,-z] ] : [ [0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0] ]; faces=[ [0,1,2,3],[3,2,5,4],[4,5,1,0],[0,3,4],[5,2,1] ]; polyhedron(points=p, faces, convexity=2); } On 17 December 2016 at 10:08, MichaelAtOz <oz.at.michael@gmail.com> wrote: > I repeat: > > Your post is still flagged as "This post has NOT been accepted by the > mailing list yet", so nobody gets it unless they look. > You need to subscribe to the mailing list > <http://forum.openscad.org/mailing_list/MailingListOptions.jtp?forum=1> , > and respond to the registration email. > > I get it as a reject as the admin.
