Hello Sean,
Content Center is not related to an MS Access, it is based on Microsoft SQL engine - for sure I will ask Content Center Developer. I am responsible for Content Center many years, believe me, I have never seen such message.
Creating part from CC As Standard/As Custom is almost same, there is API in Inventor generating IPT representing Content Center part, just folder where IPT is save is defined based on As Standard/As Custom.
I am not sure if your case is
- As Standard is fast
- As Custom is slow
If yes, it could related to an permission of folder where are you placing CC part, or an process blocking access to such folder. Or as Johnson is suggesting, some "inside" process inside your CC part (IPT) like iLogic rule.
But in general, such small family as image shows has to instance member instantly. You see family table data (family table dialog) , means Content Center provides CC data = works as expected, something strange has to be in/with IPT generated. We are sorry, we are not aware on any general issue.
