Use the tools in this toolbar to draw and edit profiles and to analyze vertical tangents and curves.
These tools are most useful for editing profiles by adding tangents and curves, or moving PVIs.
For dynamic surface profiles, most tools in this toolbar are not available. Use the Profile Entities vista to display profile data. Similarly, many of the tools are unavailable for use with locked PVIs, including the endpoints of curb return profiles.
The name of the currently selected profile is displayed at the top of the toolbar. When you click an icon, the current command is displayed at the bottom of the toolbar. The toolbar remains open if you grip edit the profile or enter another command. The toolbar closes if you either delete the currently selected profile or click the X button in the upper right-hand corner of the toolbar.
Layout Profile Creation
These three buttons control how a layout profile is drawn on a profile view.
-
Draw Tangents -
Adds a series of fixed tangents between specified points.
-
Draw Tangents With Curves -
Adds a series of fixed tangents between specified points, with free curves automatically added at the points of vertical intersection.
-
Curve Settings -
Specifies the curve parameters to use with the Draw Tangents with Curves command.
To change the default curve settings, go to the Profile Creation section of the Edit Feature Settings - Profile dialog box.
Convert Free Vertical Curve (Pass Through)- Converts free vertical curves (created with either the Free Vertical Curve (Circular) command or the Free Vertical Curve (Parabola) command) which use a pass through point as their constraint type to curves that use length as their constraint type. This command converts the constraint type of all relevant curves at once.
Note: This command does not convert PVI-based curves that are defined by pass-through point.
PVI Edit Operations
Use these three buttons to graphically modify the PVIs in a layout profile.
-
Insert PVI -
Breaks a tangent into two adjacent tangents by creating a point of vertical intersection (PVI) at a specified location on the profile view.
Click above or below an existing tangent to specify the new PVI location.
-
Delete PVI -
Creates a single tangent from two adjacent tangents by removing a point of vertical intersection (PVI) from a profile.
If two tangents meet at the PVI, they are replaced by a single tangent between two adjacent PVIs.
-
Move PVI -
Moves a profile point of vertical intersection (PVI) to a new location on a profile view.
The tangents connected to the PVI remain attached. You can also use editing grips to move a PVI.
Tangent Creation Operations
Use these buttons to add tangents to a layout profile.
-
Fixed Tangent (Two Points) -
Adds a fixed tangent between two specified points.
-
Fixed Tangent - Best Fit -
Adds the most probable fixed tangent through a series of AutoCAD Civil 3D points, AutoCAD points, existing entities, or clicks on screen.
-
Floating Tangent (Through Point) -
Adds a floating tangent from an existing entity to a specified pass-through point.
-
Float Tangent - Best Fit -
Adds the most probable floating tangent from a point on an existing entity through a series of AutoCAD Civil 3D points, AutoCAD points, existing entities, or clicks on screen. Tangency is maintained to the attached entity, regardless of how the entity is edited.
-
Free Tangent (Between Two Parabola) -
Adds a free tangent between two parabolic curves.
-
Solve Tangent Intersection -
Creates a PVI at the intersecting grade line of two tangents.
Curve Creation Operations
Use these buttons to add a curve to a profile. You can create curves by selecting entities to attach to, specifying parameters, or selecting a PVI where you want to add a curve. Parameters can be specified numerically or graphically.
For example, to numerically specify a pass-through point, enter the point coordinates. To graphically specify the point, select a point in the drawing window.
To graphically specify a curve length, K value, or radius, use the cursor to pick two points on the screen the correct distance apart. For parabolic and circular curves, you see a preview of the curve as you move the cursor. For asymmetrical curves, you do not see the preview until you begin to specify the second length.
-
Fixed Vertical Curve (Three Points) -
Adds a fixed curve through three specified points.
-
Fixed Vertical Curve (Two Points, Parameter) -
Adds a fixed sag or crest curve, with a specified K value or minimum radius, through two specified points.
-
Fixed Vertical Curve (Entity End, Through Point) -
Adds a fixed curve from the end of an existing entity to a specified pass-through point.
-
Fixed Vertical Curve (Two Points, Grade at Start Point) -
Adds a fixed curve that is defined by two specified pass-through points and a specified grade at the start point.
-
Fixed Vertical Curve (Two Points, Grade at End Point) -
Adds a fixed curve that is defined by two specified pass-through points and a grade at the end point.
-
Fixed Vertical Curve - Best Fit -
Adds the most probable fixed vertical curve through a series of AutoCAD Civil 3D points, AutoCAD points, existing entities, or clicks on screen.
-
Floating Vertical Curve (Parameter, Through Point) -
Adds a floating curve, which is defined by either a K value or minimum radius, between an existing entity and a specified pass-through point.
-
Floating Vertical Curve (Through Point, Grade) -
Adds a floating curve, which is defined by a specified pass-though point and grade, to an existing entity.
-
Floating Vertical Curve - Best Fit -
Adds the most probable floating vertical curve from an existing entity through a series of AutoCAD Civil 3D points, AutoCAD points, existing entities, or clicks on screen. Tangency is maintained to the attached entity, regardless of how the entity is edited.
-
Free Vertical Curve (Circular) -
Adds a free circular curve, which is defined by a specified pass-through point, curve length, or radius, between two tangents.Note: This type of curve cannot be created between two curves or between a tangent and a curve.
-
Free Vertical Curve (Parabola) -
Adds a free parabolic curve, which is defined by a specified pass-through point, curve length, radius, or K value, between two entities.
-
Free Vertical Parabola (PVI Based) -
Adds a free vertical parabola, which is defined by a specified curve length, pass-through point, or K value, to an existing point of vertical intersection (PVI).
-
Free Asymmetrical Parabola (PVI Based) -
Adds a free asymmetrical parabola, which is defined by specified before and after PVI curve lengths, to an existing point of vertical intersection (PVI).
Note: If the first length you specify is too large for the asymmetric curve, you cannot enter the length for the second curve. The length of the first curve must be less than the station distance between the PVI you select and the station value of the previous PVI (or end station of the previous curve). -
Free Circular Curve (PVI Based)
-
Adds a free circular curve, which is defined by a specified radius or pass-through point, to an existing point of vertical intersection (PVI).
-
Free Vertical Curve - Best Fit -
Adds the most probable free vertical curve between two existing entities, and through a series of AutoCAD Civil 3D points, AutoCAD points, existing entities, or clicks on screen. Tangency is maintained to the attached entities, regardless of how the entities are edited.
Convert AutoCAD Line and Spline
This button enables you to convert an AutoCAD line or spline to a profile sub-entity.
-
Convert AutoCAD Line and Spline -
Creates a fixed tangent or three-point vertical curve entity from an AutoCAD line or spline.
PVI Operations
These buttons control various operations with PVIs when the Profile Grid View dialog box is active. If the profile is dynamic, only the Copy Profile button is available.
-

This button enables you to extend an entity to the extents of the profile view.
Extend Entity- Extends a fixed or floating tangent or parabola to the extents of the profile view.
