I'm trying to do a cam mate and I keep getting an error stating that the surfaces are not closed and continuous to form a cam extruded from a single profile. This is the first time I've used the cam mating feature so I'm pretty lost at what I'm doing wrong. I believe that somehow I'm just not selecting all the faces of the cam but I've created and tried three different cams in my assembly and they have all returned the same error. I used the cam creation feature in solidworks 15 and I noticed that the cams are not fully defined, do I need to define them further after use of the cam creation feature? I attached my folder with all my parts and assembly, thanks for any help
