Backfaces When Using Extrude or Lathe

[ferguson4848]

When I use either the extrude or lathe tool to make a 3D object I’ve noticed that the backfacing lines show up through the ‘front’ of the object. Like below.



Now, I know that if you move the camera closer to the objects the lines seem to disappear. However, if I do this I have to zoom out to get everything in a scene in frame and it distorts the objects in the scene. I noticed that if you make a cube through the Animation drop down the backface problem is not there. In the cube 3D setting there is an option to ignore backfaces, but I do not see any such option for lathe or extrude objects.

Any thoughts would really help.

Thanks
