Hello. I am trying to find a way to export coordinates XYZ of Beam from Revit to Excel.
My problem is I’m already tried many method to do it but I can’t do anything even find the coordinates XYZ in Revit from my model.
Sorry if my question is to easy but if someone could do it, please help me. Thank you 
I would not use bounding box unless the box is aligned with the shape of the geometry, not aligned with the coordinate system axis x,y
create a curve end and start point and find the middle of the line to specify coordinates?
Beams are curve driven elements and have at least 2 coordinate values depending on the curve type. If you only want the midpoint, then get the curve of the beam using say the OOTB Element.Location node or clockworks Element.Location+ node. From this, you can use OOTB Curve.GetPointAtParameter and inputting 0.5 as the parameter value which will give you midpoint.
