how can I extract the coordinates (X,Y,Z) of the family instance from Autodesk.Revit.DB.Location/LocationCurve/LocationPoint?

[simonebehlings]

From the family instance I can extract the location (element.Location), but I don't know the next step to get the coordinate values.

I need a result similar o this:

                                       Point.X =
element.Location ->    Point.Y=
                                        Poin.Z = 

(And these elements would be beams, columns, wall...)

As you stated, there are different aprouches for line base, and pointbased components.

If the elements location is stored as a Locationpoint, you cant get the point of the locationpoint. which is of type XYZ, which has the individually properties x,y,z.

if the elmenets location is stored as a locationcurve, you can get the curve of the locationcurve. From that curve you can get the endpoint with the getEndpoint method of the curve class.

So in code that looks something like below.

XYZ point = Location.Point;
double pointX = point.X;
double pointY = point.Y;
double pointZ = point.Z;

XYZ startpoint = Locationcurve.Curve.GetEndPoint(0);
double startpointX = startpoint.X;
double startpointY = startpoint.Y;
double startpointZ = startpoint.Z;

XYZ endpoint = Locationcurve.Curve.GetEndPoint(1);
double endpointX = startpoint.X;
double endpointY = startpoint.Y;
double endpointZ = startpoint.Z;

This is how you can get point and curve from family instance depending on whatever is available from the family instance.

Thanks! I've already managed to solve most part of the problem.

I just couldn't extract the coordinates when the 'Location' property returns only 'Location', but with LocationCurve and LocationPoint I can.

@simonebehlings 

only 'Location' does not have any co-ordinates, so you can not get any spatial value from it.
This class is only used for manipulating spatially for move and rotate.

I saw that there were no properties related to coordinates in this class.
I'm thinking of another way to compare the position of two overlapping elements.
