Francisco, It seems that he line is behind the polygon -- Try, ViewPoint-> ViewPoint -> -{1, 1.5, 2.5}]. To see through we can replace the polygon with Line[{{1, 0, 0}, {0, 1, 0}, {0, 0, 1},{1,0,0}}] Allan --------------------- Allan Hayes Mathematica Training and Consulting Leicester UK www.haystack.demon.co.uk hay at haystack.demon.co.uk Voice: +44 (0)116 271 4198 Fax: +44 (0)870 164 0565 "FRANCISCO GUTIERREZ" <rpena at elsitio.net.co> wrote in message news:9e7ati$260 at smc.vnet.net... > > Dear NG: > I have the following problem.
