The command Create Sample Lines from Points draws sample lines on the basis of points in individual profiles along the alignment. Besides the classic method and the zigzag method, the function enables us to draw sample lines on the basis of a regression method. We have two options: perpendicular regression and ordinary regression.
Click on Create Sample lines from Points icon.
In Draw cross axes from points dialog box select the data source (CGS points or Civil3D points) and the layer, where the points of the cross sections are.
Define the method on which basis sample lines will be drawn and enter the left and right width of the generated sample lines.
Press OK.
