Building View Attributes issue with Mechanical Components

With a promoted Dynamic View as in the second image, the view window display is now based on Family + Part assignments, the designated Cut Plane and Forward View settings, as well as Drawing Rule overrides.  So those are the aspects you need to review instead of the active Display Style.

For example, if you had a single line rule applied to the SV you would see single line resymbolization for components affected by that rule as in the attached.

Steve,

There are no Drawing Rules Activated.

In Family+Part the toggles for Cut Plane and Forward View are OFF and I do not have an active Clip Volume in this View.

And I tested the same file with the same Dataset settings in AECOsim SS4. The Mechanical Components didn't change its display like in SS5.

So how are going about activating the BV Attributes?  

Do you mean if I toggle on the Cut Plane and Forward View? It's quite the same (wrong) display.

can you post your file??

Yes, an example would probably be best.   Your screen captures are showing that building attributes are being applied to the view, therefore Family/Part resymbolization + Display Style overrides would (or could) take place.
