Lately I’m finding myself with some revit Room/MEP Space bounding situations that make me think on the amount of area is loosing because Revit has a tolerance for Rooms/MEP Spaces and will allow small gap that the revit guys established. Basically when a column has a slight offset from the nearest wall causing a gap in the room/space bounding.
Of course there must be a reason for this tolerance but anyway how it makes me doubt of the accuracy of my models.
As Barrie Sharp explains in his blog it can reach to 449.8mm tolerance in a simple situation.
Here you have some examples of what I’m experiencing with some models:
