HI Folks -
Whenever I drop a hex-bolt, screw, or washer with properly functioning mate references they seem to stop working after a bit.
Meaning, that they seem to stop working after the first part is placed. Typically I use DRAG, COPY to place more fasteners around neighboring holes.
For some reason the mate references seem to forget to work on the next fastener. The work around to quickly open the fastener file then immediately close it then the drag and drop mate reference will snap into place again but then stops again on the next desired fastener.
