I have a master model that only contains curves.  I control the curves with a design table.  It used to open in a matter of seconds and regenerate the configurations (only 4) just as fast.  I mean it is only curves with no solid features so it should only be a blink to regenerate.  All of the sudden it takes a long time, like 4-5 minutes to regenerate each configuration and to save the part.  I cant figure out what is going on here.  I made sure there were no zeros in the table, smallest value is 0.00004.  Anyone have a similar issue?  Any help would be greatly appreciated!! I also tried it on another machine and it had the same issue.  It is a 2017 file, but I tried 2018 without any luck either.
