AHHHH!!! IT's still Disappearing!!!!
 

Oakay, I'm now merging the leg into the body and th ewhole body keep disappearing!!! :(

"Result: polySurface5polyBoolOp5. "

I've moved th elegg closer into the body, I've even gone as far is placing it right dab into th emiddle of the body and when I pres UNion, the wole body disappears. :(

Make sure your normals are all facing the same way on both objects...

MANY THANKS!!!!!!
 

GREAT, THANKS KURT!!!!:):):)

I just had to remodel the leg and not rotate the hulls and vertexes as I did before. I didn't know how to fix the normals so I just restarted the Nurbs modeling and converted to Polygons, worked like a charm!!!! Took about 10 minutes. Is there a command where I can reorient the normals if I've made them go out of alignment with the rest of the object??

MORE GREAT NEWS
 

Apparently it's not wise to stop the video from playing when you encounter a problem :o I found that the further I watched along on the dog tutorial, that you encountered the same problem as me. Will not panic next time.

THanks for the assistance Kurt. :D

I find it better to watch all the way through then take it from the top again and follow it in maya, pause when you need to and you will roughly know why you're doing what you're doing. If you get me :)

I watched all 4 parts of the dog tutorial before I started from scratch again and actually began modelling, helped me in the long run I think.
