I wrote some code to generate a polygon, it generates these two lists point = [[-36.6025, 136.603], [-136.603, 36.6025], [-100, -100], [36.6025, -136.603], [136.603, -36.6025], [100, 100], [-60, 60], [-81.9615, -21.9615], [-21.9615, -81.9615], [60, -60], [81.9615, 21.9615], [21.9615, 81.9615]] path = [0, 6, 1, 7, 2, 8, 3, 9, 4, 10, 5, 11] but for some reason, when I try polygon(points=point, paths=path) nothing is displayed. Could someone take a look at the lists and tell my why they don't work? -- View this message in context: http://forum.openscad.org/Help-with-polygon-function-tp12453.html Sent from the OpenSCAD mailing list archive at Nabble.com.

Path is a vector-of-index-vectors, not a vector-of-indices. You need to wrap it in a second set of ‘[]’: —snip-- point = [[-36.6025, 136.603], [-136.603, 36.6025], [-100, -100], [36.6025, -136.603], [136.603, -36.6025], [100, 100], [-60, 60], [-81.9615, -21.9615], [-21.9615, -81.9615], [60, -60], [81.9615, 21.9615], [21.9615, 81.9615]]; path = [[0, 6, 1, 7, 2, 8, 3, 9, 4, 10, 5, 11]]; polygon(points=point, paths=path); —end-snip-- Andrew. > On Apr 21, 2015, at 7:41 AM, cn145912 <neil.penning+openscad@gmail.com> wrote: > > I wrote some code to generate a polygon, it generates these two lists > > point = [[-36.6025, 136.603], [-136.603, 36.6025], [-100, -100], [36.6025, > -136.603], [136.603, -36.6025], [100, 100], [-60, 60], [-81.9615, -21.9615], > [-21.9615, -81.9615], [60, -60], [81.9615, 21.9615], [21.9615, 81.9615]] > path = [0, 6, 1, 7, 2, 8, 3, 9, 4, 10, 5, 11] > > but for some reason, when I try > > polygon(points=point, paths=path) > > nothing is displayed.

Renaming path to paths = [[ ... ]] or doing polygon(points=point, paths=[path]); makes the code more logical. Similarly point should be points. -- View this message in context: http://forum.openscad.org/Help-with-polygon-function-tp12453p12455.html Sent from the OpenSCAD mailing list archive at Nabble.com.
