Mastering AutoCAD Civil 3D 2008

Labeling the Surface

Once you've created the surface model, it is time to communicate the model's information in various formats. This includes labeling contours, creating legends for the analysis we've created, or adding spot labels. These exercises will work through these main labeling requirements and building styles for each.

Contour Labeling

The most common requirement is to place labels on surface-generated contours. In Land Desktop, this was one of the last steps because of the simple fact that any change to the surface required erasing and replacing all the labels. Let's look at placing labels and then modifying the style of the labels themselves.

Placing Contour Labels

Contour labels in Civil 3D are created by special lines that understand their relationship with the surface. Everywhere one of these lines crosses a contour line, a label is applied. This label's appearance is based on the style applied and can be a major, minor, or user-defined contour label. Each label can have styles selected independently, so using some AutoCAD selection techniques can be crucial to maintaining uniformity across a surface. In this exercise, we'll add labels to our surface and explore the interaction of contour label lines and the labels themselves.
