It's been in my privately kept stdlib.scad for a while... Not that's I've found much use of it. Ranges are peculiar indeed, but I've found little practical purpose to manipulate ranges, other than in a for loop. -- View this message in context: http://forum.openscad.org/ranges-to-vectors-tp7651p14404.html Sent from the OpenSCAD mailing list archive at Nabble.com.
