I am a fairly new Solidworks user and am working on a guitar neck. I have created the extrusion for the fingerboard area and the extrusion for the rounded surface where the neck joins the body. When trying to Loft between the 2 faces I am getting a rebuild error that states:

"Cannot make 2 planar end faces to cap side sheet."

The loft previews just fine then fails when executed. Please see the screen shot attached.

Searching in this error produces no results so I have to assume that this is either a rebuild error that nobody else has seen, or everyone else knows what is wrong with the part drawing and just fixes it.

Any ideas??? Any help would be appreciated.
