Rats nest / uconnected pins on symbol update.

cadSmith

Hello all,

I'm working with allegro 16.6 and am exporting a an already routed PCB design as IDF to solidworks folks.

It turns out one of the symbols in the pcb design was missing height information.  I opened the symbol in allegro and added the height info.

Then I went into the pcb design place->update symbol and selected the proper symbol.  The symbol updates , I exported the IDF, and now the solidworks folks are happy.

One problem however: the symbol's pins in allegro all have ratsnest on them now.  I can go and reroute the clines next to the pins and this seems to fix the issue, however, it would take a long time to do all of the pins and could potentially be error prone.

I'd like to point out that before the symbol update there were no ratsnest / unconnected pins on in the design and specifically on this particular symbol.

Is there anyway to connect the pins / fix the ratsnests?

 

Thanks in advance.

    It seems that more and more specs are being generated in MM, especailly with the global market, so I was finding myself converting from MM to mils more often than not.  I decided not to fight it anymore and starting building footprints in MM.  Also, quite a bit our fabrication gets done outside of the country as well, and since everybody else in the world uses MM, we just made the switch.  I admit, it is difficult at best to think in MM, especially for an old dog like me, but I'm getting there.  I even managed to get the mechanical guys to switch over to MM which makes everything go much smoother with everyone on the same page.
