Thanks guys, Once I have back face culling switched on, I can now see that there is a face missing on my model. Silly question but how do I add another face to fill this hole? Or is it a case of Merging verts? Also I still seem to be unable to paste a pic into the post, I use MAC's so the capture method is slightly different (shift,cmd,4) but the result is the same as prt scn... I am sure when you see the model you will know exactly what i am doing wrong.. Thanks again guys
