Two rooms not showing in plan

[josh.hafel]

I will do my best to explain the issue, but I have no idea what is going on. We are trying to place a room in floor plan, but when placing, revit does not show the "X" for the room's reference lines, and once placed, the Revit tells me the room is not visible in view. When I go into section or schedule, the room is visible (thouhg it is reporting the incorrect area, but thats a different issue. I can solve once the room is visible in plan...)

What I have already checked:

1. Not a workset issue, in section, the room is the same workset as the ones that are visible
2. It is not a filter. I created a completely fresh view and all the other rooms are visible except for the two in question
3. It is not a height issue, in section i confirmed that the height is within the view range.
4. It is not a phasing issue. All rooms are "Created in Phase 1"

Any other thoughts on what could be causing this?

Anything unique about the flooring in those rooms? The thickness/height of the flooring can disrupt the computation height.

Are there columns there, and a plan region?

They do not seem to be on a different design option since they show in the view...What about revealing hidden elements?

Try and delete those two rooms from the schedule and try to replace two new rooms (no worries you can undo later); what is the prompt which you get when placig two new rooms?

Thank you for the replies and sorry for the late reply. We made a recording.

@RLY_15 There is nothing special with the floors, it is one contiuous 8" slab of concrete across the entirety of level 5. We went to a different level as well that does not have units (I was thinking pehaps the floor finish was causing problems, but nothing)
@blank... There are no Plan Regions, but there is a column inbetween the units.

@RDAOU Nothing is hidden, no hidden elements to reveal and no design options. we even created an entirely fresh floor plan.

I am also attaching a video because the behavior is weird when placing the room. this happens regardless of what view we are in or what floor we are on. Its only those to room locations.

The fact that it occurs on multiple floors in the same location makes me tend toward the idea that it's based on your assemblies now (wall definitions could span multiple floors). Are the exterior walls for that suite defined as room bounding?

You also mentioned that the area found in Schedule View for that Room attempt is incorrect.....by how much?

Based on your video, this is a common behaviour when the room is concealed below a floor element either

• when the floor element has an offset (either in the host model or the link; more often the latter when multiple Discipline specific models are involved)
• or due to having a Structural level and a Finish Floor level datum and the room is hosted on the former.   

Temporarily hide your linked model and see is that reveals the room...if not try hiding the floor elements/category. If that works then you know what to fix
