![]() Pull the room boundaries to get the walls which bound the room.Get the geometry of the room, which will be a donut shape of sorts.This room will automatically be bound by those boundary lines and the exterior walls. Create a set of room separation lines just outside of the property line on every level of the building, and place a room just inside the outside edge.My old ‘exterior’ room trick works wonders here. Ideally this works on linked Revit models, but if it can only happen in the model directly that can be worked around as well. Or is there just a way within Dynamo to extract the wall area including cut opening penetrations? Building area plans have a way to identify “exterior walls” is there a way utilize this some way? Maybe there is a way to copy all exterior walls so that openings are excluded and paste as a new object for an envelope calculation? The wall types’ ‘total’ area inclusive of fenestration would be used for the materials quantity and associated waste factor. Seems like I would need a way to associate a specific window opening (and its area) to the wall it is cutting. ![]() For quantity take-offs and estimating, I would like a way to determine the total wall area of specific wall types/materials inclusive of the fenestration. Here’s where I would also like to take it a step further. This would be beneficial for ComCheck energy calculations which require the total wall area and then an input for the fenestration which ComCheck then subtracts the area from the associated wall. Ideally, there is a way to calculate the total exterior envelope inclusive of fenestration. ![]() Now, while it might be possible to create a window or door schedule to calculate the total area of those elements then add to the wall area, it might become problematic if there are interior windows or other elements that might produce and inaccurate calculation and require additional methods of filtering. However, the wall area reports actual area (so it excludes window/door openings). This assumes that wall types have their function set to exterior, and ideally, any below grade walls are either filtered by level, or set to something other than exterior. I’d like to figure out a way to calculate the total building envelope.įor example, in Revit you can create a schedule that looks at exterior walls and calculate the total area.
