Not sure why SW won't add smart fasteners to any frame on my assembly with holes but the parent one using "populate all". I used circular pattern to array to the other 5 locations in the .sldprt but when using smart fasteners in the assembly, only the parent "red" frame picks up the holes and adds the hardware. If I choose "select", I cannot choose any "red" frame but the parent one. I'm attaching the fixture and handhole frame .sldprt's, as well as the assembly. Maybe I didn't use "circular pattern" properly in the original "fixture" .sldprt when arraying the frames at 60 degrees? Thanks for any help.
