Combined polygon smooth problem

[danphan]

Hello everyone.  I am modelling a dog but have run into a few setbacks.  I modelled the torso and legs separetely, then combined the objects and merged the vertices.  I cleaned up nonmanifold geometry and conformed the normals, but when I go to smooth, divisions are created, but the the object itself is not smoothed (hard edges are preserved, even though this option is unchecked in the smooth tool options).  What am I doing wrong?  I would really appreciate it if someone could open my file and explain to me what is wrong with my geometry, I'm sure it's something!
The technique I'm using I learned from a Digital Tutors training video, called Polygon and Subdiv Modelling CD1.
Here's the scene file:

Thank you!

The problem is, that you have edges and verts that were not merged. Easiest way to check this is to select the object, hold right click and click vertex face, your model will show each face seperated, and you can see in the the front shoulder area where there is an edge on faces that should not be there. This will show you where your unmerged verts are. So just go ahead and merge those and it should fix things.

AND most of your faces are multiple... PolyCleanUp most probably wont work here properly, so just take a bit of time and manually select all faces one by one you want to have and then invert face selection, then delete. You always should take care to not duplicate objects unnoticed to prevent such mess. My shortcut for quick duplicate gives me a warning if duplicate is performed..

Thanks you both for responding! Now I understand completely what was wrong and have fixed and completed the model :). Thanks again

The finished model.  Now to rig 'im.
