Would like to see the addition of Cut planes turned on the filters tab for Conduits and can also be for other MEP services.
The reason being I use many different conduit service types all with different Colour fills to differentiate the services, in plan view this is fine but once cut the colour fill no longer shows through as you can see below.
Currently with a filter for Conduits and Conduit fittings you get the Greyed out cut tab as above, the only way to 'open' this up is to trick Revit into using a category that has this open and that wont be affected by filters this being Structural framing. With Structural framing ticked you can now add a pattern fill to your conduits. The drawback on this however is you can no longer select Filter by Service type in your filter rules which creates a big headache when drawing your conduits and having a separate parameter to get the filter to turn on.
tldr; in short please add the ability for conduits to have a fill pattern enable during cut and also have service type still selected in the service type and to top it off please let us have service types like ductwork runs do so the conduit will change to the service type with one click of a button instead of a tab select.
