FYI for some reason your walls don’t seem to show all layers in plan or 3D when they abut other objects. You can see that it works on one side of this curtain wall but not on the other for some reason - the sandwich panel is totally missing.
I’ve noticed two things will remove this problem. If the wall is redrawn with a left alignment this sometimes works, but ultimately the curtain wall has to be perpendicular otherwise it fails.
