Editing the MidlIne of a structural column

Hello, I am a bit stuck with editing the midline of a structural column. I have used the node to create this column, but when I try and look into the original node, to work out how to update it- I get a bit lost.

With the below, assuming I is the column, I can get into it and find the Curve and then the end point but I am not really sure what to do next?

Thankyou

(i.Location.Curve.GetEndPoint)

If i understand correctly you are looking for the Element Curve Component.

That Lois perfect!

Thankyou
