Frequent question: What are sample lines in Civil 3D?

In Civil 3D, section data is defined and displayed using sample lines grouped in a collection called a sample line group. The Civil 3d sample line creation wizard allows us to create cross-sections. We can create them at given intervals, and at a specified left and right distance from the alignment centerline.

Why are sample lines taken?

The sample line is used to identify the location (and width) of the section view and the data displayed within it. Once created, section views maintain a dynamic link to their respective sample lines. For this reason, if a sample line is moved, its section view will update accordingly.

How do you edit sample lines in Civil 3D?

In the drawing, click the sample line you want to edit. Click Sample Line tab Modify panel Edit Sample Line Find. Note that the Edit Sample Line dialog box and Sample Line Tools toolbar are both displayed.

How do you reverse a sample line in Civil 3D?

You can simply select all the sample line labels by Ctrl one by one then flip them and as I understood, you desire to renumber the sample line labels as well .
