I'm having a problem with area boundaries.  I have these "phantom lines" that are defining the limits of my boundareis.  Have a look at the screen capture and you will see what I mean.  The red line represents the limits of the area, but as you can see, there is nothing there to define it as that shape.

There are no area boundaries, walls, room boundaries or anything else that would cause this.  There isn't even anything to select in that general area.  I have a nearly identical floor plan on the second floor and it has no problems at all.  I have looked at the view settings and revealed all hidden objects and there is nothing there.  I even went so far as to delete all area boundaries and all areas and the phantom boundaries are still there.  Then I deleted them all once again and deleted the entire area plan and started over again, and the phantom boundaries are still there.

 What could be causing these areas to form shapes that are not even there?  Anyone have any ideas?

The issue is not the area boundary lines.  The area is being bound or defined by lines that are not there.  There are purple boundary lines that I have drawn that define some of the sides of the area, but there are other lines that "are not there" for lack of a better term that is defining the shape of the area. 

If you look at the image I attached for example.  You dcan see that the area (585 SF) is defined for the most part by the walls and the purple area boundary lines that I have drawn.  But if you look at the top left corner, there is a "line" or edge of the area that cuts across the corridor.  This "line" appears in red on the screen as the edge of the area.  But where that particular red line is, I have not drawin an area boundary line.  I also have not drawin a room separation line or any other line.  There should be no reason why the area decided to stop at that line across the corridor.  There is simply nothing there to define it.  There is nothing hidden and there is nothing to select at that spot.

For lack of a better term there is a phantom line that limits my area and I cannot delete it.  For that matter I cannot even select it or try to modify it, because REVIT tells me that there is nothing there.  Why is the area defined by lines that don't exist?  Or if they do exist, how do I delete them or even modify them?  Again, I'm not talking about the area boundaries that I have added (they show up in purple), I am talking about some sort of boundary that I did not add but is limiting my area anyway.

OK I SEE WHAT YOU ARE SAYING NOW, HOW IT JUST STOPPED THE AREA IN THE MIDDLE OF THE DOOR.

 IF YOU GOTO A AREA PLAN WILL IT NOT LET YOU SELECT THAT LINE TO MOVE IT OR EDIT IT??? YOU SHOULD BE ABLE TO DRAW A NEW AREA BOUNDARY LINE AND DELETE THAT ONE OUT.

The key here is the term Area.  In Revit, we have Rooms that have an area value and are bounded by walls and room boundry lines.  We also have "Areas" which have an area value and are bounded by "Area" lines.  Found in VG under Lines.... they are purple.

Sorry - missed your second post.. re-reading.

Did you create the complete area plan or was some of it automatic?

I think you are starting to see what I am attempting to describe.  I have tried doing what you suggest.  The problem is I cannot delete something that isn't there.  I have tried deleting every single area boundry on the plan, and yet when I redraw a new boundary in any shape it is still there.  Like I said,  I have deleted every boundary, every area, even the area plan and started over, and the phantom line still existis in the same place.

Here is another example image.  I have deleted the old area and placed new area boundaries to form a rectangle across the same area.  As you can see the phantom line cuts the area at the same place.  Once again there is no line there, just some phantome line that defines my area.  And this is just one of many phantom lines in this project.  Though for some reason only on the first floor.

Replying to WWHub:

I understand the difference between rooms and areas.  In this case I am having trouble with areas on my area plan and I am having trouble defining them.  Thes phantom lines are not area boundaries that I have drawn, though I have drawn other boundaries that define the areas as well.  I am running out of ideas as to what could be doing this.

To answer your question, the plan was originally created by having REVIT define the boundaries, but since then I have modified it so much, that very little of the original boundaries remain.  I have also tried starting the area plan from scratch, but the phantom lines persist.

BINGO!

 WWHub has figured it out.  I had another callout plan from the same level that had some random boundaries laying around.  These boundaries were affecting the other plan.  Thank you for leading me in the right direction.  I will cease going crazy now.
