I've been finding some inconsistent behaviour (when in walkthrough mode) where I "fall through" elements...
Hands in the air, I/we often re-purpose (Revit) categories for "unintended" use, (roofs for floors as an example) - and we certainly won't be changing our methods to accomodate Enscape; but nonetheless I am still curious how Enscape "decides" what can, and can't, be passed through - to at least see if I might circumnavigate any present limitation rather than wait on an update.
