    Room bounding walls & and room separators. Rooms have no boundaries?

    I have a mezzanine level that I'm working on. There is a mechanical room with four walls and then the rest has NO walls -- just hand rails.

    I placed the walls as "Room Bounding" and placed room separator lines at the hand rail/floor edge locations. But when I place the rooms, it tells me there are no boundaries. For the mechanical room, I even went so far as to make the walls CROSS each other to be sure there were no gaps -- it STILL couldn't find the boundary.

    I've attached my file (I zipped it up because unzipped, it's 10 mb and zipped it's less than 2mb).

    Does anyone have any ideas what this could be?

    TIA!

    P.S. In the attached file, I've removed everything not related to the mezzanine in an effort to try and make the file smaller (after doing a save as on my file to make this one). I've also used View Visibility to turn off the handrail so the room separators are easier to see.

    The Computation Height for the "Draw Room and Shop mezzanine floor plan" level is set to 3', which puts it at the level above. If you change it to anything between 0' and 3', it works.

      It seems to have something to do with the wall heights / levels but for the life of me I can't figure it out. If you take your mechanical room walls and make them taller the room will work but as soon as you place them to the correct height the room breaks. I made a new file and placed some 36" high walls and was able to place a room with no issues.

        Thanks anyway. I was able to get around it by turning off the Room Bounding option for the walls and placing room separators on top of them. But I'd still like to know what's causing it so that I can hopefully avoid it in the future.

        I've opened a support ticket with both my reseller's Revit rep and autodesk tech support. I'll report back with any findings they come up with.

        Of course, if anyone here comes up with something, that would most certainly be welcome. Sometimes they (autodesk and reseller) take a long time to come up with a solution (if at all).

          Our reseller just got back to me with the cause and the solution. I'll post the info here soon.

          EDIT: Well we thought it solved it. I just tried pulling the walls back down to the right height (part of the solution is to temporarily make them taller) and still have the problem.

          We're researching it. I'll report back with more later.

            Sometimes just simply cutting the walls to the clipboard and pasting them back in the exact same position will resolve this kind of problem.

              Ok. We know what caused it. Revit seems to have a minimum height for room bounding walls--that height is 3' 0 1/256". If your wall is 3ft high or shorter, then Revit will just exclude it from the room boundary object. But it doesn't tell you that it's doing that -- it just tells you that the room doesn't close and leaves you to figure out why.

              My walls were 3ft because this mezzanine isn't meant for anyone to "go up there and work" (other than to repair mechanical equipment that's up there). The area is used for storage -- I liken it to having an extremely sturdy ceiling that's used for equipment and storage). That's the reason for having such short walls.

              Anyway, I realized this morning that I had yet to put the roof on. So I drew the roof and then connected the walls (including these) to the roof. That caused the height of these walls to be above the 3' threshold resulting in the rooms closing properly.

                I just re-read Chad's message and realized that he said he was able to use walls three ft high (the same as mine) to create a room. I just did the same thing (created a new project file and then drew 4 room bounding walls -- only I made mine 2'9" just to be sure. It allowed me to create the room with those walls.

                Edit: Just out of curiosity, I tried to see just how short I could make the walls in that test file I just created before it would refuse to make the rooms. I’ve now got walls 2 INCHES high and the room object is intact. When I tried to make them 1 inch high, I got a message that it couldn’t make the walls. It didn’t even get far enough to break the rooms.

                Very odd!

                  I think I got it! Verify the computation height of the level your room sits on (it's in the instance properties of the level). If your walls are lower than the computation height, the "room bounding" won't work. Increase you computation height and it should do the trick.

                  EDIT: I just realized it was already mentioned in Post#2... I learned something though.

                    I don't know what to make of this, but I must've totally skimmed over post #2 for some reason. I saw an email message in my inbox telling me of Chad's message (#3) but I never saw one for #2.

                    Anyway....Thanks everyone! I was able to confirm that this fixed the issue.
