One really annoying thing you can’t do in Revit is the ability to schedule a wall & know its wall constraint. What is more frustrating is that the wall constraint is exposed in the API, so tools like Ideate BIM link will allow you to pick up the constrain & schedule this.
Manually, you can get around this by assigning a family parameter within the fields section of a wall schedule. Give it a name, something like “level location”. You will need to manually enter text by switching to a each plan view & select all instances of the wall type, or using the filter function to select all the walls across each view. It should not be too time consuming, but could be problematic with groups, but it does require you to follow the process carefully.
However, with my good friend & colleague Don is cooking something up which should make this whole process a lot easier. When its ready we will let you know.
