I am trying to pattern a large number of flat head screws in an assembly made of derived mirrored components. There are no "features" in the derived component to pick, so I included the hole pattern sketch in one of the derived parts. However, a sketch driven pattern will not give me the proper position of the screws, they will not sit in the countersink, but sit high. Neither "Bounding Box Center, Component Origin, or Selected point works. The screws will follow the pattern, but I cannot get them correctly inserted into the countersink position. HELP?
