Add a floating vertical curve by specifying a pass-through point and a parameter.
The illustration shows a floating curve from an existing entity (1) to a pass-through point (2) and a minimum radius (3). This curve type can also be drawn from a specified K value.
Add a floating vertical curve by specifying a pass-through point and a grade.
The illustration shows a floating curve from an existing entity to a pass-through point (2) with a grade (3).
Add a floating, three-point curve entity by best fit to a profile. You can define the best fit entity using a series of Autodesk Civil 3D points, existing entities, or clicks on screen.
The illustration shows a floating vertical curve created from entity 1 by best fit. The Xs indicate data points used to create the entity.
If you select the first half of the profile entity, the best fit entity will precede the profile entity. If you select the second half of the profile entity, the best fit entity will succeed the profile entity.
As you highlight a row in the Regression Data vista, the corresponding regression point in the drawing window is highlighted in red.
