Add fixed vertical tangents to build constraint-based profile geometry.
Fixed entities are defined by specifying parameters, such as points or minimum radius. The parameters are fixed in their position and must be edited directly.
The position of a fixed entity is not affected by edits to adjacent entities.
Except for its length, the geometry of a fixed entity is not dependent on adjacent entities.

- Adding a Fixed Vertical Tangent with Two Points
Add a fixed vertical tangent by specifying two points that the line will pass through.
- Adding a Fixed Vertical Tangent by Best Fit
Add a fixed, two-point vertical tangent entity by best fit to a profile. You can define the best fit entity using a series of AutoCAD Civil 3D points or clicks on screen.
