Ok these are two half bodies.How can I merge them at this point with the best way?


Dreamsoldier after mirror.blend (535 KB)

Delete one half
Set the object origin to the 3d curser (Origin button in toolshelf T)
Add a mirror modifier and move above subsurf modifier. Enable clipping option
Remove the faces on the line
Extrude towards the centre line

Many thanks,I tried it and it worked.Also moved the merged now lines and it moves both faces.I applied the modifier.
And another question,I pressed remove doubles and it removed nothing.That is due to clipping?

yes clipping automatically merges the two edges

Ok,I wanted a confirmation.I 'll edit this solved.Thanks!
