Add free vertical curves to build constraint-based profile geometry.
Free entities are defined by attachment to two entities, on which the free entity is dependent to define its geometry.
Topics in this section
- Adding a Free Vertical Curve with a Parameter
Add a free vertical curve between two entities by specifying a parameter.
- Adding a Free Parabolic Vertical Curve
Add a free parabolic vertical curve.
- Adding a Free Asymmetrical Vertical Curve
Add a free asymmetrical vertical curve.
- Adding a Free Circular Vertical Curve
Add a free circular curve.
- Adding a Free Vertical Curve by Best Fit
Add a free, three-point curve entity by best fit to a profile. You can define the best fit entity using a series of AutoCAD Civil 3D points, existing entities, or clicks on screen.
