Nasty lines on smooth mesh

Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Hey guys, I have a beautiful model of a murcielago coming along, and ahead of time i smoothed it out. The front looks great as seen in the perspective view, but the sides have these black outines of some geometry. I'm guessing this can be either a verticies problem when joining them or some sort of UV overlap. Does anyone know the problem and solution?

is the merge threshold when you merge vertices above 0?

I have no idea. I played around and found out that while extracting, sometimes there are extra faces. About 10 or so which overlapped. Simply deleting them and re-extruding did the trick.

Your statement abouve is the problem.

You need to set the option of Keep Faces Together on.

In Maya 7 its found at Polygons >Tools Options>Keep Faces Togeter.

In Maya 8+ it Mesh Tools Options >Keep Faces Togther.

Thank you, But I have figured the faces problem when extracting. However, onoce they are overlapping and you set the option to keep them on, the lines dont dissapear. So i needed to go in there and delete the overlapping faces and sometimes extrude again.
