Determine space or room height at a given point

[jeroen.vanvlierden]

Hello

I am writing a program that determines all room boundarysegments for given rooms (or spaces)

var options = new SpatialElementBoundaryOptions();
var segments = roomOrSpace.GetBoundarySegments(options).SelectMany(x => x).ToList();

foreach (var x in segments)
{
var c = x.GetCurve();
var p1 = c.GetEndPoint(0);
var p2 = c.GetEndPoint(1);
points.Add(p1);
points.Add(p2);
}

The z-coordinate is always 0, unfortunately. With a cubical space that is not a problem, but when there are sloping walls or a roof, I don't know the height

Wat is the best way to retrieve this?

cheers

Jeroen

you can get the room level and look for its elevation:

var level = document.GetElement(room.LevelId) as Level;

var Z = level.Elevation;

Room.ClosedShell => GeometryElement containing solid.

Get the top face of such compare with bottom face (face origin difference).

Probably there are other was such as using ReferenceIntersector.

This assumes that the room or space has the same height everywhere. And that is my problem, the height is sloped and is different at different x,y coordinates

Thanks but your answer does only work when the room has the same height everywhere

Thanks, but I don't completely understand what I need to do here...

I will probably have to intersect with the roof.

Forgot to answer my own question:

Found a solution that determines the faces of the room geometry.

After that I define a line from the given point towards a very high z-coordinate and let this line intersect with the room faces. This method works for me

public static IList<Face> GetRoomFaces(this Room room)
{
var geom = room.get_Geometry(new Options());
var geometryOfRoom = geom.OfType<Solid>().FirstOrDefault();
var faces = geometryOfRoom.Faces.OfType<Face>().ToList();
return faces;
}
