I'm slowly winning my colleagues around to the joy of using filters in views to produce schematic plans in Revit that would otherwise have taken much longer (and need constant coordination) in CAD...

So far we're doing acoustic, fire & security strategy plans using room-based parameters being read & illustrated using color schemes (note my recent post on the legends posted Friday if you will!) but recently I wanted to take the idea further and use colour filters to identify the fire rating of wall types in elevation (for building regulations' UPA calculations) ... the thing is, where previously I'd been the mug who had to do it in CAD, at least in CAD I could add a secondary hatch to denote the fire rating OVER the existing hatch applied for the surface pattern of the cladding material. In Revit, the filter overrides the material hatch - so you can't read the timber panelling (for example) behind the additional information being provided.

I did think to simply do a colour override of the surface pattern instead of a coloured-surface pattern "change", but that's not visually different enough when printed B&W (we might issue in full colour but you've always got to consider the reality of drawings ending up in B&W) - then proposed we do away with surface patterns on these strategy/diagramtic elevations altogether - but that seems a shame - especially when wanting to be as honest as informative to B.Control as you can...

We could always draw transparent-backed filled regions I guess, but that'd miss the oppurtunity of parameter-led automated work production and be a bit too much like CAD-in-Revit for me.

So, what are options might I be missing? I'd rather not set to building a library of "combined" hatch/pattern definitions along the lines of "Concrete" and a "Concrete w/ NET" if there's some other trick?
