Schedule - multi category

[rayray4105]

Hi,

At the moment I am trying to create some schedules using the Revit API. Room, wall, etc schedules seem to work fine using BuiltInCategory.OST_Rooms or BuiltInCategory.OST_Walls 

However I can not seem to find the entrypoint foor the multi-category schedule. Is there an entrypoint for multi category schedules available?

regards,

Raymond

ok, figured this out by myself 🙂 it turns out you can use BuiltInCategory.INVALID for the ElementId which creates a multi-category schedule!
