Get the XYZ point of the Room Awareness point in a Family Document

[n_mulconray]

I can easily retrieve the builtin parameter BuiltInParameter.ROOM_CALCULATION_POINT, however has anyone managed to retrieve the coordinate point for the actual point inside the famdoc that you can move around so that families are discoverable within rooms? If this is not possible is there any workaround? Does this affect the extent of the bounding box for the loadable model family?

easy:

SpatialElementCalculationPoint sPoint;

sPoint.Position = new XYZ(2, 2, 2);

Hi This is great just what I have been looking for...

Just one problem, I can't get the SpatialElementCalculationPoint reference in the family editor, do you know what I might be doing wrong?

many thanx

You have to check the Family Parameter "Room Calculation Point" , to obtain the SpatialElementCalculationPoint.

FamilyDocument.OwnerFamily.get_Parameter(BuiltInParameter.ROOM_CALCULATION_POINT).Set(1);

Thanx again I had that point covered already.

What I am not getting is the  sPoint, I don't have a lot of experience with the family editor side of the revit api. So the following i'm getting an error stating that the sPoint is not set to anything...

SpatialElementCalculationPoint sPoint;
sPoint.Position = new XYZ(2, 2, 2);

Is the sPoint derived from the FamDoc, OwnerFamily, getGeometry a builtInParameter that is cast or parameter definition? Just lost here and some background might help me from asking too many questions in the future. Plus I have googled quite a bit and found very few references to the SpatialElementCalculationPoint

[FAIR59]

the class definition for SpatialElementCalculationPoint is:

public class SpatialElementCalculationPoint : SpatialElementCalculationLocation

the class definition for SpatialElementCalculationLocation is:

public class SpatialElementCalculationLocation : Element

so the SpatialElementCalculationPoint is an Element and can be obtained by a FilteredElementCollector.

            SpatialElementCalculationPoint sPoint = new FilteredElementCollector(doc)
            .OfClass(typeof(SpatialElementCalculationPoint))
.Cast<SpatialElementCalculationPoint>()
.ToList().FirstOrDefault();

Thanx for the quick response!
