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.

    I'm pretty sure that IPC uses MM as a default now so if you build your footprints to IPC 7351 then you should be using MM as the unit. This is also incorporated into the footpint name.
