Hi all im new to this forum picked up ZB 2 about a month now. im working on a dragon model and i cant seem to get rid of the seam where the jaw meets the head take a look any help would be greatly appreciated 
It depends upon what caused the seam to be created in the first place. If it’s caused by triangles from partially dividing the mesh at a lower subdivision level, then Transform>Smooth should help you get rid of it. If it’s caused by overlapping polygons created by a poor ZSphere structure, there’s not much that you’re going to be able to do.
after trying smooth and not getting any results I started lookin in my ZSphere build and just wanted to let you know I found one small lone ZSphere tucked in with the rest of the build must have double clicked when placing the jaw decided to delete the build and start over thanks for the quick reply and your help
