Element.Location to XYZ

[Anonymous]

I'm trying to create a `List<XYZ>` or `XYZ[ ]` from a `List<Element>`.  Both `Location` and `XYZ` are members of the Autodesk.Revit.DB namespace, but there doesn't seem to be a conversion method.  Does anyone know of one, or have you created something that may be able to help me out?

Hello,

Maybe you should try Dynamo forums?

Someone answered this for me on StackOverflow:  Location to XYZ 

Also, prior to that, I was able to create this algorithm:

var fecAllElements = new FilteredElementCollector(pDoc).OfClass(typeof(FamilyInstance));

foreach (Element pElt in fecAllElements.ToList())
{
     lstElts.Add(pElt);
}

arValvePoints = new Location[lstElts.Count];
            
for (itr = 0; itr < lstElts.Count; itr++)
     arValvePoints[itr] = lstElts[itr].Location;               //PUT THEIR LOCATION(X,Y,Z) IN AN ARRAY
            
foreach (LocationPoint loc in arValvePoints)                   //GET MY (X,Y,Z)s FROM THE ARRAY...
{
     XYZ newLoc = new XYZ();
     newLoc = loc.Point;
     lstXYZ.Add(newLoc);
}

Thanks to everyone that helped, and I hope this can help someone else!!

Just saw my old code and it made me a little nauseas.  Let's maybe do this instead:

List<FamilyInstance> lElts = new FilteredElementCollector(m_pDoc).OfClass(typeof(FamilyInstance)).
				 Cast<FamilyInstance>().ToList();
List<XYZ> lLocations = new List<XYZ>();
foreach (var pFam in lElts)
{
    LocationPoint pPoint = pFam.Location as LocationPoint;
    if (pPoint != null)
        lLocations.Add(pPoint.Point);
}
