Add free curves to build constraint-based alignment geometry for the areas of your design that require maintaining tangency.
These entity types are very similar to the AutoCAD "fillet" command, but give you added control.
You can use transparent commands when you are prompted to specify direction, radius, or length, and use station offsets to specify any points. For more information, see Transparent Commands.

- Adding a Free Curve Fillet with a Through Point Between Two Entities
Add a free curve, with a specified pass-through point, between two entities.
- Adding a Free Curve by Best Fit
Add the most probable free curve between two entities through a series of AutoCAD Civil 3D points, AutoCAD points, existing entities, or clicks on screen.
