Hi,

Here i have a very basic and simple macro that demonstrate the use of the addColumnAttachment Method.

public void AttachColunm()
{
    UIDocument uidoc = this.ActiveUIDocument; 
    Document doc = this.ActiveUIDocument.Document;

    using (Transaction t = new Transaction(doc, "attach column to beam"))
	{
	t.Start();
	
    Reference myRef = uidoc.Selection.PickObject(ObjectType.Element, "Select column");			
	FamilyInstance column = doc.GetElement(myRef) as FamilyInstance;

    Reference myRef2= uidoc.Selection.PickObject(ObjectType.Element, "Select beam");
	FamilyInstance targetBeam = doc.GetElement(myRef2) as FamilyInstance;  

	ColumnAttachment.AddColumnAttachment(doc, column, targetBeam, 1, ColumnAttachmentCutStyle.None, 
	                                     ColumnAttachmentJustification.Minimum, 0);
	
	t.Commit();
	}

}

First select a column and then select a beam.

It's similar to the Revit end user interface 'Attach Top/Base' button from the Modify | Structural Columns Ribbon tab.

I hope this will help you for better understanding and how to implement it.
