Specify the fixed or floating curve to which you want to attach the tangent.
Specify the pass-through point.
To add a floating vertical tangent by best fit
You can define the best fit entity using a series of
Autodesk Civil 3D points, AutoCAD points, existing entities, or clicks on screen.
The illustration shows a floating vertical tangent created by best fit from an existing endpoint (1). The Xs indicate the data points used to create the entity.
Note: Each best fit profile entity is drawn to the vertical scale set in the profile view style. To create an accurate best fit entity, set the profile view style
Vertical Exaggeration value to 1.000 to match the horizontal scale of the profile view.

By Clicking On The Screen. Select a starting point and at least one other point. You can use OSNAP or transparent commands to select points.
From Entities. Specify the tessellation and mid-ordinate tolerance settings. You can select one or more of the entity types listed on the command line. If you selected a profile entity, specify the starting and ending station on the
Specify Station Range dialog box.
As you select points or entities in the drawing window, an X marks each regression point and a temporary, dashed line is displayed in real time. Press Enter to complete the command.
In plan view, select two or more points. Enter

As the points are selected in plan view, an X marks each regression point and a temporary, dashed tangent is displayed in the profile view.
Press Enter to complete the command.
In the
Panorama window, use the
