Pile Cap - Steel piles

[wiseup07]

I am using the Pile Cap Families found in the Revit Library. When I change the steel pile diameter, some of the piles "reverse" and go up instead of down. Anyone know why and what I can do to fix this problem?

Anyone have a solution to this?
Working in Revit Structure 2017 and having the same issue.
Using OOTB steel pipe piles and pile caps, as soon as I change the pile size, some of the flip to the top!!
Tried purging and reloading, looked at the family geometry, seems ok??

Tried putting it back to the OOTB 16" pile and went back to being ok... but any other change it filps.

Your piles aren't "flipped", you just need to align and lock all of the tops of piles to the correct horizontal reference plane.
