Yes, truss display order is set to front.
In section settings I have Fill Cut Surfaces with 'Cut fills as in settings'.
If I increase section depth of truss it appears above the composite floor also. Other objects also do not display within the composite floor depth.
I think it must be a general display settings issue but I can't see where I can affect this change?
