    Reliable families... New error in 2019

    And what a wonderfully useless one it is,

    "Constraints between geometry in the family can behave unpredictably on parameter modification. To make the family reliable, constrain geometry to levels, reference planes, or reference lines."


    ...I've got a few of these popping up during an .rfa library-save out from our freshly upgraded (2017 to 2019) .rte, and don't recall ever seeing it before.

    I'm taking the name of family next to the stalled progress bar as the offending item so am jotting them done to investigate after the run is complete, but thought whilst it chews I'd throw it up here.

    It seems to be showing up when you constrain to something other than a reference plane or reference line.

    I thought that started with 2018? Or did you skip that one altogether?

    Interesting - that's one of the golden rules - and me and my guy are pretty militant, so we'll be digging into the (12) identified next week for sure.

    Trying to get things centered (working with window trims) is where I first noticed this. I thought I was picking the reference plane but it was picking the center of one of the other nested families.

    Extending the reference lines out more than I normally do helped with that

    I didn't notice until 2018 but I didn't do a lot of Save Library before then either. Regardless, the save process seems to be more aware of constraints that reference forms instead of reference planes.

    2018 and newer are massive pains in the ass for that warning, and it bricks a ton of automated workflows that process families.

    It's a giant goddamned thanks for nothing. LOL.
