Continuing the discussion from Hatch centroid definition:

@KirkWM here’s some Python code if you want to create actual Catchment labels instead of MText.

					obj = t.GetObject(catchmentId, OpenMode.ForRead)
					if isinstance(obj, Catchment):
						labelStyleId = civdoc.Styles.LabelStyles.CatchmentLabelStyles.AreaLabelStyles[styleName]
						label = CatchmentLabel.Create(catchmentId,labelStyleId)
						output.append(t.GetObject(label,OpenMode.ForRead))
				t.Commit()
	return output

OUT = create_catchment_label(IN[0],IN[1])

@KirkWM check out Camber, my new package for Civil 3D. There are some nodes for creating Catchment labels.
