Create alignments in many ways using AutoCAD Civil 3D, such as creating them from objects, and using the Alignment Layout Tools.
When you create an alignment, you can use the criteria-based design feature to ensure that your alignment design meets minimum local standards.
Note: You can also create alignments from pipe networks or by importing them from LandXML files.
If you create an alignment using the Create Alignment From Objects command, the alignment direction starts from the nearest endpoint you click the polyline. If you create an alignment using the Create Alignment By Layout command, the alignment direction is determined by the direction in which you draw the alignment.
