    Family Origin Point

    Hello,

    Still new to Revit Family Creation, please bear with me on this question.

    So we have an older locker family that we recreated. We put the origins in the same spot. Back, center. When users go to replace the old family with the new one the whole family moves to suggest that the origin point is different. But they are not?

    Am I missing something? I would like to share with you the two families but my company will not let me. I also don't believe I can recreate the issue with a generic option. I will try, and will add to post later if I can. But wanted to get this out here first.

    Thank you,
    Michelle

    Reference Planes have a parameter named "Defines Origin"
    Only one horizontal and one vertical RP can be checked Yes. Where they intersect is where your Origin point is.

    Yes we have that. They match in the old and new. But when replacing the old family with the new one it does not go origin to origin. The new family shifts location.

    Check to see which reference planes/lines are pinned or not.

    So, if the reference planes are marked as Defines Origin, but have been MOVED from their "invisible original location," really funky things can happen. Its one thing to switch which ref plane is the Defines origin... But if they have all moved, things can still shift.

    Only fix is to move the ref planes back to where they "used to be."

    The Horizontal and Vertical Plane that is checked for Define Origin are both pinned.

    It is a whole new family. Built from Scratch. not sure what you mean though by their invisible original location. The two families the origin matches on both. It's in the same spot. Didn't move it.

    That you know of. It could be off in the Family Templates.

    Can you post the two families?

    If you have AutoCAD you can create an X (crosshair) at the WCS origin of the file. Import the DWG into the family, using origin to origin. It if lands at the intersection of your reference planes then the origin is in the same place. If not then you know the reference planes have been moved, at some point, away from it.

    This helped us solve the issue. Thank you so much! It seems the template we are using was changed up and the origin point was moved.

    But I thought there wasn't a "hidden" origin point in the file? I thought it was only where you defined the origin to origin?
