- Unconnected Height
This is really worrying because it means that when a wall is attached at top or bottom, the "Unconnected Height" is almost certainly going to be displaying a false value in the properties dialog box, and in the schedule.
|Unattached wall with correct Unconnected Height property|
|Attached wall top with wrong Unconnected Height property|
In the properties dialog you can see those "Attached" checkboxes so it might alert you to the issue, but that does not help in a schedule, as you cannot display those properties there.
This also occurs when a wall has been attached to a gable end roof (or any angled roof)
Edit Wall ProfileThe same problem could also happen if a wall has had its profile edited - again the wall heights could be scheduling false values.
Basically, when you schedule wall heights using the 'Unconnected Height' property, it could be a pack of lies! If we could also schedule the "Attached" properties of a wall, then we could use the schedule to identify attached walls, and perhaps use conditional formatting to highlight possible false height values.
One alternative solution is to create a calculated value of Length x Unconnected Height to get the supposed area; this can be compared to the actual reported area (built-in property). If they are different then you know that the wall has been either attached or had its profile edited - therefore the 'Unconnected Height' property is unreliable.
You could take this a step further by adding a comparison calculation
You could then do some conditional formatting to make any dodgy wall heights easily apparent
One other thing you could do is reverese engineer the height by adding a calculated Average Height - This would only be accurate for rectangular walls, as those with sloping tops or edited profiles would still not be accurate - hence the use of the word 'Average' in the calculation name. I would use this solution with caution - perhaps only where walls have accidentally been attached to floors above.
