iLogic Assembly Missing parts in drawing

[Cosmin_V]

Hi everybody,

I have an iLogic Assembly whit 3 parts, in some situation parts ar suppress or invisible, or features are suppress in parts.

If all parts are visible and unsuppressed if I open it in a drawing I can see only one part in "Hidden Line" Style what ever what Style I set.

If I suppress this part then I can see the others but only in "Hidden Line" Style.

Why this is happen?

I try to open it on several computers but same.... 

I use Inventor 2016

Many Thanks!

To me is sounds like the assembly and/or the parts of this assembly has a BOM structure of reference.

Is the line style actually hidden (dash-dash) or a phantom line style.  Long line-dash?
