Wall.ByCurveAndHeight at different levels (for stepped terrace)

[Der_Jon]

I’m trying to create walls that are placed at different levels.
I was expecting that it’d work like the floors where even if I placed the level at ‘e.g. Level 2’, revit automatically computes the offsets for me in order to place it where I want it to be.

What happened instead was that all of them were created at certain level. Any idea how to fix this?

The walls are supposed to go here

Try first to play with lacing and list@level on the Wall.ByCurveAndHeight node…

Thanks! It Worked.

Just wondering why it worked though (@L1 and Cross product). I mean even if it accessed the deepest level of the list, it should still apply Level1 right? I have no idea why this worked.
