How to retrieve Section View / elevation view Marker Current location from its location property (marker.Location)?

[akahay]

I am trying to move the view markers (e.g. section view markers, or elevation view) in the active floor plan view to given the position. However, I am stuck at trying to find the marker current location then use the Location.Move(move_vector) method to move it to the new location which is determined by move_vector = (NewLocation.X -CurrentLocation.X, NewLocation.Y -CurrentLocation.Y,NewLocation.Z -CurrentLocation.Z). Please help advise on how to retrieve the current location of the marker or show a better way to achieve this?

#Collect all the markers
markers = FilteredElementCollector(doc, doc.ActiveView.Id).OfCategory(BuiltInCategory.OST_Viewers).WhereElementIsNotElementType().ToElements()

for markr in markers:
	markr.Move(NewLocation) # this works but it moves the marker 10 unit on X, Y, Z respectively but not to Point(10,10,10). I would like to move it to Point(10,10,10))

OUT= "None"

Hi @akahay 

 you need to find the original position point of the elevation marker and then find the translation vector with newLocation using (newLocation-orignalLocation) and pass this vector to below method.

ElementTransformUtils.MoveElement(doc, element.Id, translationVector); 

Translation vector => Distance x Direction ( if you want move 5 unit from (0,0,0) position in x direction means then your translation vector will be (5,0,0).

To Find Original Position.

Element Marker is a Revit type element, so you need to calculate the center point of the element using bounding box, set it as a original location.

Reference C# Code

///Get Original Position of the Elevation marker
BoundingBoxXYZ bb = e.get_BoundingBox(doc.ActiveView);

///Get the center of the BoundingBox
XYZ origin = (bb.Min + bb.Max) / 2.0;

///New Location for the Elevation marker
XYZ newLocation = new XYZ(14.2032460977063, 49.7652126901109, origin.Z);

XYZ translationVector = newLocation - origin;

Transaction moveElemeent = new Transaction(doc, "Move Elevation Marker");

moveElemeent.Start();

DirectShape ds= DirectShape.CreateElement(doc, new ElementId(BuiltInCategory.OST_GenericModel));
ds.SetShape(new List<GeometryObject> {Point.Create(origin) });

ElementTransformUtils.MoveElement(doc, e.Id, translationVector);

moveElemeent.Commit();

Hope this will helps 🙂

Thanks, Mohamed, for the response. I just had time this week to implement your solution. Your solution is partly working for my case because probably my . However, I am able to leverage the BoundingBox node in dynamo and use the information to get the center point of the bounding. Then still use, the marker.Location.Move(TranslationVector) to move the marker. Really appreciate the response!
