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.
