wall based family under level behaves incorrectly

[PieterL_TM]

Hi everyone,

I have a wall based family which will be used to connect two wood panels (walls).

The issue occurs when changing the 'below_level' parameter.

In the family editor it behaves correctly, but when loaded into a project the family moves up rather than down.
How can I solve this issue?

Control the under_level by Elevation from Level is the easiest way.

I know this is possible, but I have the same issue in other families in which I clearly want the parameter to offset the height compared the the reference level, so this isn't a good solution for my situation.
