Un-deletable Room Separation Lines

[Anonymous]

Hello, I am having an issue where invisible, undeletable Room Separation(RS) lines are changing the boundary of my room. I think that it may be a bug because I have tried many ways to see the lines and delete them but to no avail.

Note: attached image shows the random diagonal RS lines (circled in red) that are mysteriously present and undeletable. 

Things I have tried:

1) Making sure construction phase is "show all"

2) I have filter selected all RS lines and deleted them but the mysterious room boundary still remains....

3) I can draw new RS lines that impact the room boundary and delete them, but the invisible lines still slice through my room boundaries screwing up all sqft calculations no matter how many new lines I draw.

4) I have also checked visibility graphics->lines settings. All are on. 

5) Restarted software

6) Revealed hidden elements

7) Hid every object (but those lines still impact RS boundary).

Thoughts: this seems to be an object specific issue (other RS lines can be added and deleted at will).

Thank you for any suggestions that you have to rid myself of these invisible, undeletable RS lines.

Room or the Room Separation Line?  Rooms can only be deleted through a Room Schedule.

- Do you have thin finish floors higher than the Level?
- Do you have walls above the cut plane?

My original question/issue addresses an odd room boundary situation that I assume is driven by invisible room separation lines that cannot be deleted. In addition to the troubleshooting I mentioned previously, I have also deleted all rooms in the project through the room schedule, but when a new room is added to this space, invisible room separation lines (presumed) are still impacting the room boundary just as happened before (shown in attached image). My finished floor is 3/4" above the level. Although when I hide the floor, no RS lines are present that would create a weird room boundary shape like this....... I also do not have any angled walls above or below the view cut as has been asked. All nearby walls are orthogonal.

I have just addressed your points in my response to ToanDN

There may be old room separation (RS) lines in the project because this problem is occurring in other areas too. I cannot find or delete them per attempts in prior post. The room boundaries Revit is giving me do not make sense (see attached image to this post showing another image of the same plan).

Ah! I have seen this posted about on two different occasions.  One of the OPs even posted his RVT for us to test. I couldn't figure it out. Drove me crazy! Maybe it is a bone fide bug. You ought open a support case on it through your Autodesk Account Portal.

Keep us posted if you do.

Thanks so much for the quick responses everyone! This has been driving me totally crazy

It could be that those lines are at a different level either below and are masked by floor elements, or placed above the cutting plane and therefore nowhere to be found.

After testing for the usual (visibility of line and room separation categories, phases and worksets). Draw a room separation line outside your project > go to an uncropped 3d view with everything visible > select that room separationline and all instances > isolate elements in view with the little glasses button below your view > Spin around until you see it.

Before deleting it see the reference level it was placed in. 

Let me know how that works.

I once had an intern that modeled ceiling coffers using thin walls to resemble gyp.board in section. He wanted to close gaps in ceiling planes with varying heights.

Looked good and was kind of overkill BUT he did them with room bounding walls, and those were causing all kinds of problems with room areas and wall joints.

As the design progressed some of them were left in the ceiling plenums by other team members that were unaware of them, it took about 12 hours just to find and get rid of those.

Look in your plenums, make ceilings transparent and you might find a few surprises.

So you managed to fix it?

The issue was solved by following the advice of psemrau..... I created a new RS line, went to 3d view, selected similar through the filter, found the old RS lines embedded in the floor. They must have been on another level despite being assoc. with the floor on which I was working. That is probably why when I deleted the RS lines in plan I could not get rid of the hidden ones. Working in 3D worked. Thank you!

Thanks for sharing! Also don't forget to mark his post as the solution.

If anyone has this issue again, be sure to change your View Range so that the bottom view range is at or below 0, on the associated level.
