Creating Curves

Curves are an important part of surveying and engineering geometry. The curves you create in this discuss are no different from AutoCAD arcs. What makes the curve commands unique from the basic AutoCAD commands isn’t the resulting arc entity but the inputs used to draw the arc. Civil 3D wants you to provide directions to the arc commands using land surveying terminology rather than with generic Cartesian parameters. The Figure shows the Create Curves menu options.
