Bolted Connections Follow Pattern IV 2013

I have an assembly comprised of 2 identical parts that have holes in a radial pattern.  The holes were created at the part level, & the holes are obviously in both parts (they are not created by the bolted connection).

I've made a bolted connection using the "By hole" option & I've checked "Follow pattern."  The bolted connection is made without any problems, & the "Follow pattern" populates all the holes as would normally be expected.


However, here's the problem:  the only bolt/nut/washer assembly that appears to be fully constrained is the one on the base hole (by "base hole" I mean the hole that I initially selected).  The other bolts/nuts/washers are not constrained to the holes.  So, I can drag the entire pattern & it spins radially about the axis of the base hole.


I've never seen this ridiculous behavior before IV 2013.  Am I the only one???

Unfortunately, it's known Inventor Bolt connection behavior,as a work around, you can RMB the bolt connenction and check grounded option.

Thank you for your response.


Grounding could be a workaround.  You could also constrain the axis of one other bolt to the axis of one of the other holes.  Neither of these are really acceptable, though, because they ruin the adaptability of the bolted connection.


Is this 'known behavior' new to IV 2013, or did it happen in previous versions?
