I am working on a t-slot frame assembly with fasteners and cut frame pieces. I put the majority of the fasteners in with the copy with mates functionality. I had to modify the frame a bit and the fastener mates are complaining. The error is that the mates are over defining the assembly and it makes no sense becase I have a concentric and distance mate to the t slot surface. Has anyone ever had this problem? I have attached the model.
