	How to use spline as a breakline in Civil 3D?
	You can easily convert a spline curve to a polyline of the same shape and use this polyline for your terrain model (DTM). Use the `SPLINEDIT` command and its option "convert to Polyline". The `PLINECONVERTMODE` variable specifies whether your spline will be converted to arc (1) or line (0) segments. You can do the same in older AutoCAD and Civil versions with the SplineConvert utility.
