Dear members,

                              We want to modify family instance pipe length which both side connected by other connector elements, that middle pipe length did not change when we try to change it forcefully the error message popup as per image attached. Kindly help us to resolve this issue.

While change family pipe length as shown at image the error message popups at Revit 2023

How does Revit know whether to move one fitting up, or the other one down, or both by half the distance etc?

You’d be better changing elevation of one of the elements then Revit knows how you want the system to flex.

Dear @iainsavage,

Revit models are done with appropriately. Its works correctly in Revit 2019 Version when you change the length, Same behavior not followed in Revit 2021 / 2022.

Please suggest.
