Unenclosed rooms madness

[patricks]

We have a church project with a large addition to an existing church building, and then the interior of the existing building is getting completely rearranged. So all interior walls of the existing building are demolished, exterior walls remain, and then there will be new interior walls in the existing building.

So I was working over in the addition area, did several things, and suddenly noticed when I zoomed out that ALL new rooms in my existing building have become "unenclosed". I checked all the walls, and all have the top and bottom constraints at the same level, and the room objects are all on the same level as the walls. All walls are still set to "room bounding", and yet they don't seem to be enclosing anything.

I know it's something simple I'm overlooking. What could it be?

Some more info:

The existing building has 2 different floor levels, one 6" higher than the other. The lower level is called "Orig. F.F." and the higher level is called "Sanc. F.F."

Now the main floor plan view I'm working in, which has room color fills showing, is set to the Orig FF level. The Sanc FF level does not have a plan view associated with it. All the rooms on this Sanc FF level are the ones saying it's not enclosed.

I discovered that when a room object has all 4 surrounding walls set to the base constraint of Orig FF, then it becomes enclosed. But when it's set to Sanc FF (which is the correct base level for these rooms), it becomes Not Enclosed.

It appears that when a room object is placed, it references whatever level your plan view references to. It does not reference to the current work plane, and you can't change the level reference of the room object.

So I made another plan view referencing the Sanc FF level (6" higher), placed room objects, and it seemed to work.

But here's what's crazy! I opened a previous version of the file from yesterday, and all rooms are enclosed correctly, DESPITE the walls sitting at Sanc FF and the room object referencing Orig FF. What is the deal??

[patricks]

I just started a blank project, drew 4 walls, placed a room object, then moved the base of the walls up 6", even 12" and the room remained enclosed as it should.

So I don't understand why a difference of 6" of the wall's base level is affecting these rooms being enclosed or not.

Patricks,

Please check the type parameters of your Level element. (Select it in an elevation view for example).

Uncheck "Automatic Room computation height" and set a height (measured as an offset from the level's height) to something reasonable. It is useful if you set the plan view's cut plane height to exactly match that height to see where the room bounds are.

Automatic comp height is set to 4' by default, but based on various connectivity analysis it occassionally changes to 0", which I suspect is the case in your model.

(You can simulate this by setting comp height to 0" manually and see if rooms start to become unenclosed.)

Please let us know if it made any difference.

Rooms seemed to behave normally in a new project, even if the bottom of the walls are above the room's associated level, and the levels are set with Automatic Room Computation Height turned on by default.

Haven't had a chance to try it in our actual project. My boss is actually who is working on it, not me, and he already created an additional plan view from that Sanc FF level to deal with the room enclosure issues.

This probably wouldn't answer how you got into this to begin with but moving forward, instead of creating a new level for the 6" difference, could you use a Plan Region and adjust the view range to relate to the lower/upper level?

[patricks]

Why would I not want different levels? The existing building was built at different times with different floor levels.

I created the 2 different floor levels way back several weeks ago when I was putting the existing building into Revit. The problem we're having now just happened yesterday while my boss was working on the new addition portion of the building.

I had a similar problem. It turns out that I had edited the wall profile in elevation view. Part of the wall was not at 0'-0", which happend to be the computation height. And because the modification was below the cut plane it never occured to me where the "leak" was in the room enclosure.
