Building views / visibility settings

Question

About a year ago I filed SR 7000192083 regarding problems where objects were visibile through slabs. I didn't really understand in the first run, why this happened, so I filed the SR. 
 As Bentley is clearing its backlog of SR's, we're getting back on that issue now. 
 Anyway - as the issue develops, it's apparent that Aecosim uses material settings for forward views and not level settings, regarding transparency (which controls if you see through an object or not). 
 Didn't fully understand the reply from support, but it seems that they think this behaviour is intentional. 
 Quit sure that this deviates from the behaviour when using drawing extractions. 
 Any opinions on that one?

Yes, that's exactly what you should be seeing! The Threshold and Material values should work in conjunction with each other. Whether that's a change in later builds I honestly don't know (or remember) but I'm glad it's not working this way for you. 
 
It's not the same as DEM, as Thomas noted, but DVs are a different animal in many respects being live geometry and not specific to Building but available to all disciplines (including base MicroStation).

As Eric mentioned there are cases where one may want "transparency" in Drawings, which is what the default system provides. 
 
But as Thomas mentions this can be controlled via the Transparency Threshold slider per Display Style. So for something like Forward-Drawing perhaps that threshold slider can be increased or turned off (as I know Thomas prefers :-)).
