Feature Line Labels

Feature lines labels use the general multipurpose line and curve label styles. The Autodesk Civil 3D NCS drawing templates contain several useful styles, including Gradient Only and Slope Only.

Setting Downhill Arrows

The default Gradient Only label style displays the gradient using a direction arrow that points in the forward direction of the feature line.

Use an expression to configure the direction arrows in this label style to point in the downhill gradient direction, which may be more useful. To do this, edit the Arrow component of the Gradient Only style, as shown in figure 6.
