Walls of the room

How to retrieve the sorrounding walls of a room ?

I know the boundary curve can be obtained, but the boundary curve is the inner edge of the wall. But I need the wall LocationCurve.

Thanks,

From the BoundarySegment you can get its Element, which is the element which is bounding the room (typically a Wall or Room Bounding line).

As a side note, you can change the settings that control how Room Boundaries are reported to use the Wall Centerline, etc.

Could you elaborate more on this?
Also, is there a way to do the other way; i.e., writing the code so that when assgining rooms in Revit, the room boundary lines are aligned with wall centerline or exterior face?

Hi Matt:

I could not get your point. "Change setting".. Is that can be done by API? If so can you please let me know about it in detail.

Thanks in advance,

Hi Amirek1:

Yes I eloborate my problem.

When I export the rooms, I export the room boundary curves also. This is done by getting the Room.Boundary way. But here I get the boundary curves as the inner edges of the wall footing.

Now When I import the same again, I get the room boundary curves as the edges only. So when I tried to create the walls using this curves, the walls are offset and interfere/placed apart. This is because, the curves are automatically taken as the center Location curve of the wall.

There seems an other way creating a room boundary without walls. It is by "Room Separation lines"
So I tried to create the "Room Separation" lines using the current edge curves.
I used the method NewRoomBoundaryLines() which is available in the Create namespace.
But adding to my worries, they are produced as Space separation lines only.

Any suggestions would be great :)

Disclosure: I have not fully tried this - but here's my theory.

If you change the Revit settings under Settings + Area and Volume Calculations, you can make it so that when Revit returns you the boundary lines for the room, they can be in any of a few places (wall face, wall center, wall core center, etc).

This setting can be changed programmatically.

So I was suggesting that if you change the setting, you would get the boundary lines in a way which would support your creation of walls (which currently have to be created on center through the API).

Yes. I find by its category.
But Category is "read only".

Is that any way to change its category?

No, there's no way to programmatically change the category I think.

Well, I saw a linestyle can be set for the ModelCurve, but I could not get the available styles in application. Any idea how can I iterate the linestyles?
